I created an account while in the store with an email of [email protected] and a basic password and surprisingly didn't have to verify the email. Then turned on a VPN to my house.

I plan on just creating a new account every time I go in just to fill up their database with nonsense.

You do realize that they are actually tracking the device itself by the hardware MAC address and other device fingerprints.

The email is just a bonus to let them legally spam you. Anti-spam laws have an exemption. If there's a prior business relationship like shopping in their stores, they can put you on their spam list unless you opt out.

Bogus email only helps for spam but doesn't do anything about tracking.

EDIT: For Android when there's a Captive Portal like the screen shot. devices will use Persistent randomization which while not the hardware MAC will remain the same for the same network where they can track your visits.

Pretty much all modern phones randomize the MAC address everytime they connect to a network unless the user explicitly says not to do that.

+1, had issues using Android devices for presence detection because of this very useful privacy feature. Even on your home network, the MAC address and device hostname get randomized, unless disabled in the settings

Edit: typo
