Well i took a look around yesterday and found amazon to be the cheapest. I spent 60 quid and got all this:

Final Fantasy X-2 (ive seen my freind play and both of us dislike it but ill complete it anyway)
Guides for:
Final Fantasy VII
Final Fantasy VIII
Final Fantasy IX
Final Fantasy X
Final Fantasy X-2

No idea why i bought the guides first, but in a few weeks ill be buying the games.

Is there guides for 1,2,4,5 and 6?
