This morning I pottered into sainsbury's to buy Christmas cards, fruit and the secret of eternal youth (strangely, they didn't have the last item).
At the till I paid for said items - minus the secret of eternal youth - and glanced at my receipt.
Sainsbury's is counting the VAT reduction in with your money off in three for twos and stuff. So it looks like they're giving you an even bigger bargain.
Cheeky monkeys.
