UK shoppers redeem more than 1,500 money-off vouchers every minute, or 2 million every day, saving £2.7bn per year.
According to research by price comparison website moneysupermarket.com consumers save more than £56 per month each using the vouchers.
The site found that the use of shopping vouchers rose 6% over the last six months and 38% of consumers use a discount voucher twice a week or more.
54% of those polled said that they used vouchers on a regular basis for clothes.
In the run up to Christmas 46% of those polled said that they would use discount vouchers to buy presents.
A moneysupermarket.com spokeswoman told the Telegraph: “Our research showed that the vouchers are becoming an expected and valued part of our shopping routine. A few years ago it would have been unheard of for people to pay for Christmas presents using vouchers - now almost half of us won’t be shopping without them.
“It’s a clear reaction to living in more cash-strapped times when retailers and restaurants are desperate for us to spend with them and must offer discounts in order to compete.”
