Kmart offers the Microsoft Xbox 360 Wireless Bluetooth Headset
, model no. 22J-00001, for $19.99
. (This price will show at final checkout.) That's tied with our mention from two weeks ago (which was for pickup only) as the lowest total price we've seen for this headset. (It's a current low by $7.) It's compatible with Xbox LIVE and Bluetooth-enabled devices and features ear gels, an ear loop, and up to 8 hours of battery life.
Update: It's now available for in-store pickup only.
