Queensland retailers achieved a high level of compliance with Queensland Fair Trading laws during a pre-Christmas statewide compliance blitz.

Fair Trading Minister Margaret Keech said the vast majority of retailers met their refund and business name registration obligations during Operation Tinsel.

"Investigators checked compliance with the Business Names Act 1962 and the Fair Trading Act 1989," Mrs Keech said.

"They spot checked 396 retailers and issued 41 warnings for very minor infringements and just three infringement notices.

"This result is pleasing as it clearly demonstrates that most retailers are getting the message about doing the right thing by their customers and the law.

"The Christmas and New Year's sales rushes are a bonanza for many retailers but can also lead to customer complaints and requests for refunds.

"Refund signage should not mislead customers into thinking they have no right to claim a refund, and signs with statements such as 'No Refund' or 'No Refund on Sale Items' are illegal. "

Mrs Keech said customers are entitled to return goods with proof of purchase and ask for a refund, exchange or repair if the goods they bought:

• had a fault that the buyer could not have known about when purchased;
• were not the same as the description provided by the salesperson or advertisement;
• did not match the samples shown to them; or
• did not do what they were supposed to do.

"Satisfied customers will spread the word of their positive experiences with your business, improving your reputation and ultimately, your bottom line," she said.
