Walmart Patented a Way to Price You. Not the Product.

Walmart picked up two patents this year, one in January and another in March. Machine-learning systems that forecast demand and recommend prices off your previous purchases, your payment method, and your customer ID.

Not the product's cost. You.

Lindsay Owens laid it out on Jon Stewart's podcast this week. Her new book Gouged digs into exactly this.

Pair those patents with the smart carts rolling into grocery stores (scan as you shop, skip the line) and the store watches what hits the basket and moves the number on the fly. Grab the tuna and the mayo two aisles over quietly costs a little more, because the cart already knows you're making tuna salad.

Walmart says relax, the patents are about markdowns, not surveillance pricing. Maybe. Companies rarely patent a thing they never plan to use.

Online they've been charging us different prices for years and we never noticed, because we weren't standing next to each other at the register. The smart cart drags that trick into the building.

Independent grocers and small operators are sleeping on this. You will never out-data Walmart. You don't have to.

You can be the store where the price on the shelf is the price everybody pays. In a world of prices that follow you around like a repo man, one honest number is a position worth owning.

The loyalty app was never the discount. You were.
