For sale only:
XBox 360 Slim 4GB (like new, boxed with all parts, etc, includes receipt - purchased 23/11/10)
Kinect (like new, boxed with Kinect Adventures!, callibration card, USB extension cable, includes receipt - purchased 25/11/10 - no power supply as not required for a Slim, so I gave this away)
£100 each collected from Milton Keynes, very easy route of M1 Junction 13, 14 or 15.
I have over 1000 feedback across other forums and will provide relevant details to the buyer to verify.
For postage, the buyer can sort out their own courier so it is at your risk and cost based on the service you select (items will be packed securely) otherwise Royal Mail Standard Parcels with £250 insurance looks to be approx £15 for both items. Will need to pack, weigh and verify.
