They should have exchanged it for you for the price it says on the till purely out of goodwill. It's got £2 off RRP at the moment i think, ring 0845 604 6543 and then follow the options to speak to someone about it. they will contact the store for you probably about going back in, we exchange without a reciept alot this time of year it's how it is after christmas. No point refusing and upsetting people, unless it's an opened DVD and they're trying to refund that, definate no no !
