Cheers for the warning mate, they seem a little expensive to me anyway.
However i suppose you have to remember you are buying 2nd hand parts, and trying to return them 2 months later.... i don't know of any large and reputable company that would willingly take returns 2months after the purchase date.
And for this reason you will not get very far in the small claims court. Have a read though the companies terms and conditions and you will probably see the problem.
Rob,
