So that'd make it $249 + $50 GC + $40 TIV. Not horrible.
I assume you're talking about the Vita Madden bundle since you mentioned the $50 GC. If so, Madden 13 for the Vita trades in for $12. It's $20 for the 360/PS3 versions. Those are base values, so $24 for the Vita and $40 for the consoles. Add another 10% of the base value if you have Gamer Club Unlocked membership.
