Cheapskates paradise!

I was rummaging in the Pound Shop today looking for crappy folders for putting dvdr's into, and saw one of these. Something you have hanging on your keys to stick in the trolley at ASDA's (in lets be honest, the rougher areas of town) saving yourself the somewhat dubious inconvenience of reaching for a pound coin (thats sitting in your pocket). Not sure I'd want my house keys hanging off the trolley though, particularly in the supermarkets where they INSIST you pay for one before coming in... rough.
