Why Your Grocery Store Wants Your Phone Number

One grocery item can carry two prices. The lower one may appear only after you enter a loyalty number. Why does a store work so hard to attach that number to an ordinary basket? This documentary follows the deal from shelf to checkout to a linked receipt, then into the retail media business that helps brands target ads and measure purchases. It also asks who funds different kinds of discounts, why app-only coupons can be harder to use, and what evidence does — and does not — show about different prices for different shoppers. 00:00 The price that asks your name 02:36 Who pays for the deal? 05:24 The identified receipt 07:37 The other customer 12:35 The deal you can actually use 15:41 Three meanings of “different price” 19:21 The bargain at checkout 21:08 Like and subscribe Selected primary sources and original investigations: Kroger FY2025 Form 10-K (63 million households, more than 95% of transactions linked to a loyalty card, retail media): https://www.sec.gov/Archives/edgar/data/56...
