  • I heard about strategies to print your own barcodes and stick them on merch to get a "discount". And that was intended to fool cashiers.

    Imagine if I don't have to think about a cashier doing this transaction. $2 steaks for everyone!

    • You’d need to figure out a similarly weighted item. The majority have a lookup table of “this barcode is this weigh range” which prevents scanning a single almond and putting a TV down.
