Bargain watch
Take care with marked down items in the supermarket- barcode relabelling works both ways. If the label with the marked down price doesn't cover the original properly, the laser will usually read the original in preference to the dodgy, black on yellow one printed by the handheld re-labeller.
If this happens in Tesco, take the item and receipt to the customer service desk and you will get the price you paid back and keep the item free. I got 24 cans of dog food free that way once, because the checkout guy scanned one can and multiplied by 24 instead of scanning the pack price. Other supermarkets will only refund the difference in price.
On the other side, I used to be regularly undercharged on four-packs of orange juice as the four-pack barcode label often did not cover the one printed on one of the single containers. It got pretty tedious trying to get the staff to do something about this each time. The inertia of the human element is all that holds back the millennium.
