Damn, with all those exclusions it is pretty crappy of EBStop to charge $9.99 on top of the 2 Xbox 360 trades! They've eliminated all the cheap games, the least they could do is make it trade 2 get 1 (without the $9.99).
In fact, it seems like in many cases you would get LESS than just trading the games straight up + 10% Edge bonus. Just like with the Dirge of Cerebus "bonus" they are taking advantage of people and actually providing LESS credit for a number of games.
For example, say you were to trade GRAW and Oblivion, 2 games which they list prices for on the web site and aren't brand new titles - thus ones people might use for this deal. You would get a base of $58 + Edge bonus of $5.80 for a total of $63.80. If you use this "deal" they will make you pay $9.99 and then, if you aren't savvy, steer you towards a USED copy of whatever game you are looking for (which only costs $54.99). So instead of getting the game + $8.81 left over, you lose your two games and $9.99. Wow, great deal there

.
I don't even have an Xbox 360 and I loved their trade 3 get an extra $5 promo, but they are starting to piss me off with these last couple of "deals".
