• At least they’re telling you. There’s also a lot of hidden surveillance in stores - they’ve done it with Bluetooth and cameras for some time. Things like monitoring how long you look at products and evaluating your reactions to displays.

    • That’s why I always introduce a good bit of entropy to my shopping patterns:

      -Enter and go straight to produce
      -Spend 20 minutes examining eggplants
      -Walk up and down 5 aisles pausing exactly the square of the aisle number in seconds.
      -Grab a box of tampons
      -Grab what I need as quickly as possible
      -Return tampons
      -Checkout and leave

      Somewhere a marketing team is spending hours trying to figure out how to improve the conversion rates for tampons and eggplants for customers in my demo.

      • Don’t forget to flick and knock on various fruits and vegetables. Randomize how many flicks/knocks per item, and throw in a few on produce items that normally don’t get that kind of test e.g. grapes or potatoes.
