I bought battlefield 4 for xbox 360 at a local store, they dont offer the $10 upgrade like the big stores do. The stores I saw looked like you had to buy the original (xbox 360) game there in the first place, which I didn’t. How do I upgrade without buying the 360 game in the first place at one of the big stores (best buy, target, gamestop). I saw that the microsoft store had a deal where you bring your reciept in, but will my receipt from the local store work? or do I have to have a receipt from the microsoft store?
