EB TIV might be like $30-20. You could try to maximize that with Power Trades towards Alan Wake, Trauma Team, Blur, ModNation Racers, Alpha Protocol or MorphX (never even heard of this last one), that might give you $45-30 TIV. Or go for one of those $49.99+ used games and get $20 on top of your TIV.
I'm not exactly sure about this game. I love the POP series, but I got burned by POP 2008. I enjoyed the game, but it dropped in price really quickly and that's a trend for Ubisoft games. Assassin's Creed II have had sales for a few weeks going for $40-30.
