I tried to do the trade in 2 and get Uncharted 2 for $19.99 and told him which games I wanted to use, but he said that it would only apply which ever promo was better. Wanted to use Skate 2 and CoD:MW2 so I might have to go back and see if they can fix as I see it charge me $59.99 for the new item. Maybe because he took my trade-ins on the same transaction.
A few changes I noticed from last I used list (before bonuses):
Skate 2 $9.50
Red Faction: Guerrilla $14.25
Prince of Persia $3.50
Afro Samurai $4.75
Syphon Filter Dark Mirror $0.80
