Looking at selling my old Xbox 360 Slim (250GB). Bizzarely CeX are offering £79 cash which seems more than any of them are going for on eBay. That's according to online. If I take it in tomorrow in my lunch break am I likely to actually get that? I take it I need to sign up for a membership as well, is that easier done online or can I potentially avoid it in-store? (Bearing in mind I want cash, not vouchers). TIA.
