This deal includes 1 XBOX 360 controller & a receiver for PC. The receiver allows connecting maximum 4 360 controllers to a PC, also allows you to use XBOX 360 wireless headset on your PC.
I saw the post on this forum that a gamepad is 17.98 on GAMESTATION. The receiver can then be counted as 11 pounds.
I've found every big website, GAME has the receiver for 14.99 but out of stock. Play.com has the receiver for 25 pounds. Cheapest on ebay is 19.99+2.99 delivered (not very reliable though). I also make some research, the receiver has been discontinued by MICROSOFT, I don't know why, but it's quite hard to get one at this price (11 pounds).
