Can i return an unwanted game within 10 days to Gamestation if i still have the reciept? I used to do this on occasion a couple of years ago don't know if anything has changed.
If you mean play it for 10 days,finish it then return it,i doubt it very much.
If that is something the used to do,its no wonder they went in to administration.
If the game is still sealed and unused then i would say yes you should be able to get a refund or store credit depending on their rules.
