alt Hacker NewsProbably mostly dangerous for the user, or are people routinely writing their own price signs in the store and then "buying" it for less? Walking up to the lot at the car store and crossing out some zeros? Don't see how this would be any different.

What they do is swap bar codes, or they code organic fruit as regular, or they "forget" to scan in the self checkout, but yes.

Back in the day people used to swap/edit price tags a lot. Also making fake coupons with the same knowledge. It was a pretty common and easy form of shoplifting since all barcodes used to do was just encode the pricing/discount information.
