The economics of bulk buying|
I saved some pennies at Tesco's the other day, by trying to self-scan 12 cartons of soya milk. The machine got terribly confused and kept saying "remove the item", "replace the item", "item double weighed" etc. I followed its instructions dutifully, but when I got home I found I'd only been charged for 9 cartons. Hey ho.
