My first job was at coles a few years back now. For a while they stocked some dodgy tv's. When they went on special, for some reason, they scanned at $5. Since it was store policy that if it scans incorrectly, the first item is free and subsiquent items are for the lower price, many poeple got some really good deals on tv's. Since then they changed their policy so it only affects products under $50. Was pretty funny at the time though
