i have a few questions for this thread.. umm 1. does the halo3odst/forza3 combo pack work for this deal? i mean i would get about $20 for the combo yet $40 towards smg2 or rdr? 2. if i do this trade in for the preorder, then cancel do i get the value back or the $40 in credit? i would really like to trade in my combo pack or one of those games with motorstorm since it only trades @$9 but jumps to $20 with this deal to get smg for about $10.
