Ok, so gamestop is still selling halo 3 USED for 50 dollars and they say it might not even have a book or case! My question is will halo 3 price drop (how much) after christmas(how long after approximately) Thanks.Or besides eBay, where could i get a cheap halo 3? My friend said it is possible to save the game to ur 360 harddrive if you have the cd is this true? If so, i will borrow his halo 3 and save it to my harddrive.
