The report, which covers six major product categories and 49 subcategories, also shows that heavy digital coupon users (defined as the top 1/3 of redeemers) are among the most desirable shoppers, spending 50 percent more per shopping trip and $3,171 more per year than average shoppers. The major categories covered are Food, Beverage, Personal Care/Baby Care, Household Care, Health Care, and Pet Care.

The prolific shopping of digital coupon users becomes more noticeable when examining just "stock-up trips," or occasions when shoppers spend $75 or above. Digital coupon users make 48 percent more stock-up trips than average shoppers: 19.5 per year, compared to 13.2. Heavy digital coupon redeemers make 169 percent more stock-up trips annually, for a total of 35.5.
