Child of Eden is a lovely thing that I've been waiting for. It's also a new thing, which means that it's going to be full price. Except at Amazon! Amazon has the Xbox 360 title for $15 off today, priced at $35, on sale.
Amazon has other stuff on sale in the games department: Alice: Madness Returns for $39.99, Brink is $36.99, and The Witcher 2 is just as cheap. Also, all Ubisoft 3DS games are $10 off. There's more of them than you think! Petz 3D, baby!
At Buy.com they have a 12-month Xbox Live starter with headset and keypad for only $59.99. That's $15 off. They also have the Kinect bundle with Kinect Adventures for about $20 off.
Finally, Newegg.com has the Wii Rock Band 3 keyboard and game bundle for $39.99.
Go buy some sh*t! At least get that Child of Eden while it's cheap.
