Shoppers over-spending by almost €500 a year chasing supermarket discounts

46% of shoppers surveyed have agreed to ‘buy one get one free’ or ‘three for two’ sale offers, which leads them to spend more, with 30% of shoppers believing supermarket loyalty schemes and money-off vouchers also lead them to waste food. File picture

Irish shoppers could be overspending by almost €500 a year "chasing" supermarket voucher discounts, new research suggests.

The study by Coyne Research, conducted between June 21 and July 6, with 1,000-adults sampled, found half of Irish shoppers claimed to have intentionally overspent, shopped more frequently or bought something they didn’t need to qualify for supermarket money-off vouchers.
