Our Tesco's has scan-as-you-shop scanners, so you can scan your own shopping and pay at the end. I love them. They are quick and easy, and you don't have to keep unloading and reloading your shopping.
However, today, I scanned a pack of baked beans, and it came up with a banner saying "2 for £3". So I got another one. For some reason I checked my till receipt at the end. Did I get two for three pounds? Did I arses.I was annoyed enough to queue at the customer disservice till and got a £6.50 rebate, so I'm not out of pocket, but I bloody well think this is fraudulent of Tesco, to not automatically charge the prices that have come up on the scanner. It is obvious that the scanners use a different price database to the tills, God knows why, and the two are out of synch.
I bet most people never check. I never have before.
