So it seems that my house has been cursed in the last month by a PC killing witch. Either that, or 3 PCs just decided to die all within a month of each other. I'm going with the witch thing. Anyway, I was able to re-use one windows 7 key as it was retail and I had bought a Windows 8 key when MS were doing them cheap. But now I find myself about to build the 3rd PC and wondering where the cheapest place to get a retail Windows key would be. I've checked out the obvious places but I don't fancy paying £150 if I can help it. Of course, I could go OEM but recent experience kinda makes me want to grab a copy that can be transferred if I want to upgrade the mobo/cpu... So, am I missing something? Is there a cheaper way to buy (legally), or do I just have to bite the bullet?
