I ordered Frontlines the other day when it was on the madness deal and I was curious to what its price was after the sale so I went to GoGamer.com. I noticed that the price for it wasn't the $29.90 or so during the sale, but instead $34.90. I checked some other games and noticed a few that were potentially good deals, since they're all in original retail packaging:
Xbox 360
WWE SmackDown! vs. RAW 2008 $34.90
Ninety-Nine Nights $13.90
Rainbow Six Vegas 2 $39.90
Frontlines: Fuel of War $34.90
Guitar Hero III (game only) $29.90
PS3
Turok $37.90
I didn't go through every console, but here is what I found from the 360, PS3, and Wii games they had for sale. Dirt cheap shipping starts at $2.99, and I've ordered from them in the past with no problems. I think they're based out of California though, so anyone ordering on the east coast might have to wait a while for the shipping.
