Product: Tesco Finest Chicken Breast with Rocket Sauce & Asparagus.
Barcode: 5 051008 990461
Replacement barcode (sticky label): 9715 0510 0899 0461 4001 7504
Discounted price: £1.75
Respacing the replacement barcode, we get:
971 5 051008 990461 4 00175 04
Hmmm.... it's the original barcode with a few digits prepended and the new price added at the end. Are they insane?
With a couple more examples, I think it would be trivial to create Tesco discount labels at will.
Surely encoding the discounted price of an item on the barcode is a pretty stupid thing to do?
