Not content to merely offer the program in their own stores, Microsoft will expand its pilot program – which offers 4GB Xbox 360/Kinect bundles for $99 with a two-year subscription to Xbox Live – to two new retailers. Later this month, the program will migrate to all U.S. Best Buy locations and select GameStop stores.

Microsoft’s own Larry Hryb (also known as Major Nelson) announced the expansion on his website, writing:

This next phase of the pilot program will be limited in terms of both timing and the number of units available—we’re excited to forge new ground and explore a new retail model for Xbox 360, but also want to emphasize that this is a pilot period for the program.

Originally initiated in May, the Xbox pilot program offers Microsoft’s blockbuster console at a reduced price at the outset, allowing people to buy a bundle containing a 4GB Xbox 360 and a Kinect accessory at a reduced price. The program requires a two-year enrollment into Xbox Live at $14.99 a month. Not a bad deal if you don’t have the system already.
