There's no sign of this deal on the Big Lots website (or anywhere else currently that I can find), but this is apparently a repeat of a deal Big Lots offered this past May. I picked mine up in Oxnard, CA where they had a wall-long shelf packed with PS3, XBox 360 and Wii versions. I've been able to confirm availability (as of 10/10) in 12 stores across Southern California, Arizona and Nevada.
Amazon.com price: $79.88-89.88 depending on platform.
Included in box: DJ Hero Game, turntable controller w/ hardshell case that doubles as a stand. Exclusive Jay-Z/Eminem 2-CD set (with collectible case designed by artist Shepard Fairey) including unreleased (as of the game release) tracks.
