alt Hacker NewsSure, I was asking about membership discounts (e.g. people who shop at this store and are "members" get 10% off everything compared to "non-members"), vs loyalty programs with individual product electronic coupons/promotions, which aren't covered by this bill.
Typical European loyalty programs offer spend-based ‘points’ accumulation which can be spent as a discount later. Additional offers on top of that like ‘bonus points on product X’ or personalized offers based on purchase history add to the degree of variation in how much individual customers end up spending.
