W-lmart has their new "plus" subscription program to compete with Amazon Prime. One of the perks is "scan-and-go". You use your phone to scan your items as you shop, then go up to a self checkout, scan a QR code on your phone, get your receipt and bag your groceries.
This seems ..… very easy to take advantage of. Anyone try it yet? Im thinking maybe go and bag as you ship in reusable bags, "accidentally" missing a bunch of items, then paying or walking out quick. Or else scanning and bagging as you go then walking right out.
Too bad almost everything at the one I normally go to is locked up, might take a drive out to a less jail-like store.
