When it comes to coupons, it turns out millennials haven’t yet given up paper for digital.
Despite the popularity of Groupon and other online discounts, 18- to 24-year-olds are actually about twice as likely to hand over a piece of paper for a price break than to either enter a discount code online or use a coupon on their phone, according to a recent survey by CreditCards.com.
Among those with credit or debit cards, almost half said they used a coupon found in the newspaper or snail mail, or printed from the Internet; 26% said they use coupons on their phone, while 22% have entered a discount code online.
More broadly, the paper coupon market has been surprisingly resistant to online competition. Almost two-thirds of the survey respondents said they use paper coupons, while 17% use online discount codes and 15% use their phone, the survey found. Overall, 85% of Americans said they use coupons at least every now and then.
Expect paper coupons to keep losing market share, though, as the slow tide of mobile technology takes over, says CreditCards.com analyst Matt Schulz. Purchases made on phones — with or without coupons — are expected to grow to $626 billion worldwide by 2018, up from $204 billion last year, according to one Goldman Sachs forecast.
