This is a YMMV deal, as a local Target store had a handful of The Beatles: Rock Band Limited Edition bundles for the Xbox 360 on clearance for $175.  Amazon also has The Beatles: Rock Band Limited Edition bundle for $169.99 as part of their Deal of the Day.

The Limited Edition bundle includes:

• The Beatles: Rock Band software
