A good website for windows upgrades

Upgrade windows 7 to 8: This is what is on the Microsoft website

Windows 8 Pro Upgrade - Student Offer Student price £49.99 incl. VAT
Windows 8 Pro N Upgrade - Student Offer Student price £49.99 incl. VAT
This has the letter N which must stand for something but the description is the same so is the price

Windows 8 Pro £189.99 incl. VAT
There is no upgrade price for this from Windows 7. Also some products say upgrade from XP or Vista. Seems Windows 7 is not upgradable.

The website is rubbish for product selling and there is no information about lists of shops on the hi street in the UK to buy from but I have heard that PC world is one. Who are the others.
