If the goods are faulty we will meet our obligations under the Consumer Guarantees Act. There is no law that requires a store to give you a refund if you change your mind. The Consumer Guarantees Act may entitle you to a refund from the seller where the goods have a major fault. The Act does not apply if you have only changed your mind about the goods. The policy may state that if goods are returned within a certain period , and proof of purchase can be provided , a refund, exchange or credit note will be given.
Stores have different policies from one another.
Don't assume that because some stores have refund policies they all will. If in doubt ask them about their return policy. 14 days proof of purchase required - this is likely to be the register receipt although an EFT POS receipt or credit card receipt may be acceptable if it shows what type of goods were purchased. Some stores may change their policy for special promotions, for example, on sale goods . Or the store may alter its policy in your favour because you are a frequent customer.
