Every little helps

Today I learnt about a great deal that Tesco do. No, not BOGOF on Robinson's squash (although that would be a great deal) but 'double the difference'. Basically if they overcharge you then they double the difference and give it to you back. So when I paid £15 for Monsters Inc even though there was a £7 sticker on it, Tesco doubled the difference and refunded me £16.

Thanks Tesco!
