Just been looking through some games on play.com and there seems to be a dodgy seller on there called business1. The seller has 1 feedback which says the seller did not send out the item. I contacted him asking why he didn't send out the item and the reply was because it was xmas so he refunded? Anyway this seller is listing popular games at stupidly low prices. I believe him to be a scammer.
Just a warning to think carefully before buying anyway.
