A contract is a legal agreement between you and the person from whom you are purchasing goods or services whereby they agree to sell to you those goods or services and you agree to pay for them at an agreed price or at an agreed rate.

You should always be wary of contracts where you do not know what your final costs will be, although in some instances costs will vary in the course of the provision of the works or services so it is not always reasonable for the seller of the services to give you a fixed price.

However, as far as possible do not proceed without a written quotation setting out precisely what goods or services are to be supplied to you and what they are expected to cost. 

How do you know you have entered into a contract?

Both you and the seller of the goods or services must intend to make a legally binding agreement. That is, you must agree to purchase the goods or services and the seller must agree to sell them to you. There must be an offer and an acceptance. An offer must be made by one party and accepted by the other.The offer may be made by you as the prospective purchaser but in most cases purchases from stores involve you selecting goods which are already marked with the price on them.

However, merely marking the price on goods does not constitute an offer to sell. The offer is made by you when you ask the seller to sell them to you. The contract is made when the seller accepts your offer to purchase the goods. There is a good reason for this. If putting a price on goods constituted an offer to sell the goods to you and the goods were mispriced you could accept the mispriced offer.

This places sellers at a disadvantage. Contracts may be accepted in writing,orally or by implication eg: handing over the goods and tendering the money for the price. However there are many ways of making contracts.

For an offer and acceptance to be valid there must be something known as 'consideration'.Consideration means that each party must give something for what they get. This normally means that you get the goods and services and the seller gets what you pay for them.

However, a promise to pay is sufficient to ensure a contract and it is not necessary for money to change hands. Accordingly, you cannot rely on the fact that you did not pay for the goods as the basis for saying that there was never a contract.

To enter a contract you must have what is known as legal capacity. If contracts are entered into by persons who are mentally unable to understand what they are doing, or in some instances for people under the age of 18 if they are unable to understand the nature of the purchase the contracts will be unenforceable. However there are circumstances under which people under the age of 18 can be held to contracts.

Contracts for illegal purposes or illegal goods or services may not be enforceable. For instance if you purchased a service which involved the seller committing an offence the contract is unlikely to be enforceable.

However, in some circumstances contracts for illegal purposes may be held to be enforceable if other penalties are provided and the courts hold that the illegality is only incidental to the nature of the contract which would otherwise have been legal. Purchases of illegal goods are usually held to be unenforceable. 

The need to have contracts in writing

Where everyday purchases are made at supermarket check-outs and local stores,it is neither practicable or necessary to provide for a contract in writing and it is usually the presentation of the goods together with presentation of money which will be sufficient.

Similarly, many small contracts are verbal eg: Buyer: 'May I have a can of Coke?' Seller: 'Yes that will be $1.20" (Offer). Buyer: 'Thank you I will take that'

( Acceptance). However, when larger purchases are involved it is, especially for services, it is advisable to obtain a contract in writing. 


What are door-to-door sales?

When someone calls at your home to try to sell you goods or services this is known as a door-to-door sale.

Because door-to-door salespersons call at your home without invitation, the Door-to-Door Sales Act gives you protection which you would not receive if you buy from a shop or if the door-to-door seller comes in response to your request.The Door-to-Door Sales Act does not apply to goods and services bought for business purposes or sellers acting on behalf of charitable organisations.However, a follow up visit arising from an unsolicited phone call will be covered by the Door-to-Door Sales Act.

Under the Door-to-Door Sales Act salespersons are not allowed to call except from Monday to Friday between 9:00am to 8:00pm and on Saturdays between 9:00am to 5:00pm. Salespersons are not allowed to call on public holidays. 

What if I do not want the door-to-door salesperson to visit?

You can ask them to leave and you do not have to allow them into your home.You are not obliged to buy anything from them. You may ask them why they are calling and ask them to show you an identification card with their name and the name of their employer. 

What happens if I decide to buy?

What happens depends on whether you buy goods or services worth more than$50. A written contract is not required for goods and services valued at less than $50.00. However, the situation is different where:

  • goods or services are worth more than $50 or,
  • if the contract price is not known when you enter into the contract because you may have a right to cancel the contract after certain services have been provided or at any time after a certain date or the contract may be for an ongoing supply of goods but you may have a right to cancel the contract after you purchase some of those goods.

In these circumstances, you should receive two notices. One explains your right to cancel the contract and the other is a notice to complete if you decide to cancel the contract.

Contracts for goods and services above $50 must be printed or typewritten and have to include the salespersons full name and address or that of the supplier of the goods or services, the salespersons signature, the details of any services performed, the total costs of the goods or services or details of how the costs will be calculated and a statement immediately above where you sign which says 'This contract is subject to a cooling off period of 10 days'.There is no cooling off period for insurance contracts or credit contracts.

You must be given a copy of the written contract once you have signed it. 

What if I change my mind?

There is a 10 day cooling off period from the day you sign the contract for you to cancel the contract. During that 10 day period the salesperson must not accept any money or perform any services for you even if they leave the goods with you. If you want to cancel the contract you must post or hand the notice of cancellation to the salesperson or supplier of the goods or services and if goods have been left with you you should return them or let the salespersons'supplier know where to collect them from.

You should keep a copy of the notice you send and note the date on which you posted it. If you lose the notice you can still cancel the agreement by writing to the salesperson or supplier. You do not have to tell the salesperson or supplier why you are cancelling the contract.

If the 10 day period has expired you will only be able to cancel the contract in certain circumstances which involves the salesperson acting properly by accepting money or providing services before the 10 day cooling off period or contacting you outside the permitted hours or by harassing you into signing the contract. 


When can I return goods?

You can return something for either a refund of the monies you paid, repair of the goods or replacement of the goods if the goods are defective, the goods are not what was described by the salesperson or in advertising, both generally or at the place where you purchased the goods, or you let the salesperson know why you wanted the goods and the goods are not fit for the purpose you told the salesperson you wanted them for.

You do not have a right to a refund because you bought goods which are the wrong size or you changed your mind about the colour or decided you just do not like the goods any more. Some stores will give you a refund or exchange the goods for other goods or give you a credit note. They are not obliged to. 

What if I return the goods and I only want a cash refund?

If the goods were faulty or inaccurately described or not suitable for the purpose you made known to the salesperson you can insist on a cash refund and you do not have to accept a credit note even if the store has a 'No Refund'sign.

Do not be deterred by no refund signs as no refund signs only apply if you bought the wrong size, colour or changed your mind. They do not apply when the goods are faulty, improperly described or not fit for the purpose which you told the salesperson you were buying them for. 

How long can I keep the goods for before I demand a refund?

This depends upon the nature of the goods. For instance it may be considered unreasonable to purchase an article of clothing to wear and wash it numerous times and then to ask for a refund because stitching comes loose or the like.

Each case needs to be decided on its merits but there is a difference between a defect and fair wear and tear. The nature of fair wear and tear depends upon the type of good purchased and the use to which it is put. It also depends upon the type of materials of which the goods are made.

In some cases goods may need small repairs. If the seller is able to make those repairs without difficulty, the seller may be able to insist on repairing the good rather than replacing it. 


Certain trading practices are prohibited by State and Commonwealth legislation. The State legislation in Western Australia is the Fair Trading Act 1987 and in the Commonwealth the legislation is The Trade Practices Act.

Unfair trading practices can include misleading or deceptive conduct,unconscionable conduct, selling goods which are not fit for the purpose for which they are sold, selling goods which fall short of the way they are described or are not as good as the sample shown. The same applies to services which are not rendered with due care and skill.

The Fair Trading Act and Trade Practices Act also prohibit sending unsolicited credit cards goods and services and certain types of trading schemes such as pyramid selling schemes. 

Misleading or deceptive conduct

Misleading or deceptive conduct is conduct which may lead you to believe that goods or services have certain characteristics or attractions which they do not,or lead you to draw conclusions that are inaccurate. You do not have to prove that the conduct was deliberately intended to misled or deceive you. It is sufficient that a reasonable person would have been mislead or deceived by such conduct.

Suppliers and advertisers of goods and services cannot claim that those goods and services have standards or qualities which they do not, are endorsed by persons or organisations when those persons or organisations do not endorse those goods or have uses or benefits which those goods do not have.

They are also not allowed to make statements about the place of origin of goods or services which is false or misleading. They cannot accept payment for goods and services if they intend to supply goods or services which are different to that which it was intended they would supply. 

Unconscionable conduct

When one party who is a stronger position to the other in a transaction and takes advantage of that position the actions of the stronger party may be held to be unconscionable conduct in trade and commerce.

Some persons have however a significant disadvantage because of factors such as age, mental capacity, limited understanding of written or spoken English and the like. When the stronger party knows or should have realised that the weaker party did not fully understand the transaction but proceeded with the transaction anyway such conduct may be seen to be unconscionable conduct.

Some forms of coercion or harassment in the use of sales techniques which lead to one-sided contracts may be viewed as unconscionable conduct. 

Pyramid selling schemes

If you are invited to enter into a trading scheme in which you pay money to participate in the scheme and receive benefits in money or goods for recruiting other participants to the scheme and the scheme operates mainly to recruit new participants this scheme may be a pyramid selling scheme which is illegal. These schemes are outlawed because in many circumstances most people who participate in the scheme lose their money and very few benefit. 


Who is responsible if the goods are damaged when the goods are being delivered?

If you purchased the goods and made your own arrangements for delivery the seller will not be liable if you damage those goods whilst transporting them yourself. However, if the seller arranges delivery for you it is the seller's responsibility to deliver the items in good order and any damage in transit will be the seller's responsibility.

When the goods are delivered you should inspect them to ensure that they have been delivered in good order. If you are not home when goods are delivered to your home you should make some arrangements for someone to be present to collect the goods.

If you or no-one else is home the seller may return the goods to the store and charge you again if a further delivery has to be made. 

What if I or my children damage goods in the store?

You will not necessarily be liable for every circumstance by which goods are damaged. If goods which are easily broken are left in high traffic areas,protruding from shelves or otherwise placed where it is likely that the goods would be damaged by normal everyday shopping use, you may not necessarily be required to pay for the replacement cost of the goods. However, if you or your children pick up goods or knock goods over and damage them you may be held liable for their replacement cost. 


The Internet has become very attractive to shop because you have access to a wide range of goods and services. You can browse and purchase when you want to and in some instances you can purchase direct from suppliers rather than through retailers.

However before purchasing on the internet you should consider the following:

  • You are not physically able to inspect the goods and the goods may not be of the quality represented on the website.
  • Whilst you are able to purchase on a world-wide market it may be difficult to obtain after sales support servicing, warranty, replacements and refunds.
  • You do not necessarily know whether you are dealing with reputable persons who will actually supply the goods you order.
  • You will be required to make payments providing credit card details.
  • Information you supply may become widely available to others.

The things I should look for

Sometimes it is advisable to ring or e-mail to follow up about the goods or services to be provided. Make sure the sellers give proper contact telephone numbers and address numbers including a physical address that you can reach the business at later. Do not rely upon post office box addresses.

Check out more than one shopping site for the goods you want before making a decision. Often special or limited offers are available on more than one site and available for longer periods than stated.

Find out how the goods are to be delivered, what the delivery costs are likely to be and whether the goods will be subject to any sales tax, import duty and the like.

Find out what the goods will cost in your own currency. Find out when the goods or services will be delivered and what the seller's policy is on refunds.

Note that it may be illegal to import some goods from overseas into Australia. 

Using your credit card

Check whether the seller has a secure payment system and if not, arrange to give your card number by telephone or mail. Do not give bank account details as you will risk unauthorised withdrawals. Print out your purchase details and keep a copy.

With credit card purchases check your monthly statements to see you have been charged the agreed amount and if you dispute the charge complain to your credit card provider immediately.
