I got so bored of not having coins for trolleys recently I bought one of these things. Not used it for a trolley yet, but the local chickenshop does 2 hot wings (but puts three in the bag) for £1 and doesn't take card for less than £5 so has basically become my wings token and I couldn't be happier with that.
Rather than buying one having you considered just calling a promotions company and getting them to send you a sample of their supermarket trolly keyring coin for free?
