Just bought this from Asda 2 days ago, played it for an hour or so and realised its not for me. Can i take it back, even though its out of its cellophane wrappping?
I have the reciept and would prefer the cash rather than an exchange.
If you don't like it then you don't have an automatic right of refund - you depend on the shop's good will (unless it's bought online). Asda will be within their rights to refuse, but it's more than likely that they won't especially if you offer to exchange.
Edit: As MichaelPook says above your best best is to say it doesn't work, but that doesn't automatically mean you'll get your money back.
