I have a nintendo wii and I'm not sure if I should get a Xbox 360 or PS3. Most my friends have a wii or ps3 so I'm leaning towards a ps3 but I want to try out an Xbox 360. Is there any store that will let me buy it and IF I don't like it will let me return it within a few days for a full cash refund? I don't mind if it's second hand or new. In fact I would prefer second hand.
