I recently did since the item I was purchasing scanned for more than what it was labeled on the shelf.
Had to take the cashier back to the aisle to prove it......
That’s happening more frequently. I’ve used that mismatch twice to my advantage at a certain Big Box store.
For example, the price on a fancy light bulb was $8.98 if you believed the shelf, and $29.xx if you believed the bar code scanner. I used my cell phone to snap a picture of the publicly stated price. Then talked to management. Showed them the photo. And said, “This is what I saw with my own two eyeballs. Therefore, this is the price you advertised. The price you must honor. I don’t read bar code.”
I know, I know, they SAY that the bar code price is the real price. But since when did THEIR incompetence become MY problem?
