if its windows 7 your looking for ,I would say that for example any offer you see offering windows 7 home premium (the most commonly bought) for say less than £70 full version. I would be suspicious of . unless you are a student ,(some student deals are much cheaper) there are countless websites springing up ,some in the UK but many outside ,and using co.uk addresses . offering keys at rediculous prices . they are mostly scams ,yes you will get a key ,but it wont stay activated for long . also if you buy a key from microsoft ,the price will be almost the same as the complete package (box 2discs ,guide etc.) my advice is to allway buy from a reputable dealer ,and get the whole package . I have at my disposal all versions ,but the truth is the home premium version will do everything 99% of us want or need .
