A friend has just pointed me to this link; Oxfam now have an online charity store which includes books! Definitely worth a look as this is the first online second hand bookshopping experience I have seen that gives the money to charity.
I will be bookmarking it for future use; I'm still sticking to my book-buying ban and will update you on my progress tonight.
