Why Amazon.com?

From the editor: the links here point to Amazon sales pages. The reason? I trust Amazon! I have personally bought many books and a laptop computer through them and every time the delivery has been much earlier than expected. One time a book did not arrive for over a month, so Amazon just sent me another one! The original which had been lost in the post (through no fault of their own) eventually did turn up and when I asked if I should send it back to them they said don't bother and just donate it to the local library. I can rest easy when recommending them!
