A soon to be released study from Coupons.com, in conjunction with GfK Knowledge Networks, to identify the shopping behavior of the digital coupon user, shows that digital coupon users shop more frequently and spend significantly more during each trip than the average U.S. consumer. Based on more than 200,000 households using digital coupons, and compared to 2.3 million shoppers, tell us that "...brands wanting to reach heavy grocery spenders... (should) strongly consider digital coupon sites as an important piece of their coupon and brand advertising market mix..." says Neal Heffernan, SVP/GM, Behavioral Insights Group at GfK Knowledge Networks
