I traded in Bigs 2

/

towards Dragon Age: Origins and my total came out to $18.86 after tax. I almost complained when I saw that I had only received $18 (after Edge) for each game. In my mind, I was expecting to get $21.50 (after Edge) for each game. Then, I saw that DA:O was $49.99 and not $59.99. I received the trade 2 get an extra 10% promo (7922) instead and ended up paying $13.99 for DA:O.
I went to another GS and traded in Bloom Box and Bigs 2 for NSMB Wii and the computer there was giving me the same promo (extra 10%). I told the clerk and the manager had to manually adjust the trade-in total to $20 (before Edge) for each game.
I apologize if this was asked in the previous thread but I noticed that the list for the COD:MW2 deal includes Lego SW:CS

as an eligible title. I didn't see it in the exclusion list. Has any one had any luck using that game for the trade-in offer?
