A cashier in Boise guessed my grocery list before I typed it, and I just stood there
I was scanning my own stuff at the self checkout on a Tuesday and the app already had my coupons loaded for things I had not even picked out yet. Does the algorithm know me or is this just what loyalty cards do now?
Oh wow, that app is just pulling your past purchases and guessing what you need again. Check the settings in that app, you can usually turn off the "smart" suggestions if it creeps you out like it did for me.
