Briscoes is defending its sales practices after the Commerce Commission warned retailers not to mislead customers.
Briscoes Group managing director Rod Duke told Mike Hosking there's nothing illegal about the retailer's promotions.
"No, there's nothing wrong with it at all so long as you don't have the same merchandise on sale all the time. That's the problem with some retailers.
Duke said some retailers are pushing boundaries when it comes to constant discounts, but he said Briscoes is complying with the law.
"We've been in business in this country for 155 years, I've been with the company 30 years, and we've had no prosecutions. I think if you spend enough time, you spend enough money and you take it seriously yes, the system works."
