Abebooks are an umbrella organisation linking together 2nd Hand bookshops all over the globe. So no matter what book you're looking for it's very likely that the Abe Database will have a copy somewhere.

If you're looking for a rare or unusual book try abe books.

I've noticed that many of the Cornish Bookshops have their books listed on this database, so you stand a good chance of finding that rare Cornish History book.

Amazon offer a huge range of books, both new and used, from numerous international publishers. I use Amazon on a regular basis and am always impressed by their efficent service.

If you're looking for a new digital camera then Amazon is often worth a look, if only to have a figure to compare against elsewhere.

I swear by my Canon A70 Powershot Digital Camera, and this is the company I bought it from. It offers some of the cheapest camera prices on the net and with online trackable delivery - it's great.
