Where is the cheapest place to buy XP online? Or, in a store, if it's in the UK.

Thanks.
Check out newegg or any of the other places like that. Try to look for an OEM/System Builder's copy. Those are usually the cheapest. I don't know if XP is still for sale though...isn't the cut off for sales this month?
 
Tiger Direct.

There may be some good deals on eBay, or you could buy from someone on MR.
