As a man with more books than is good for him (or the house) I do list books I no longer want on Amazon as a seller. Not all of them as some (most) aren’t worth anything - a lot of books are listed at 1p and the seller makes a bit on the postage. By the time amazon have had their cut that’s a quite small bit.

Selling on ebay makes more as their cut is less BUT with amazon you don’t need to mess around with photos & flashy listings. Just a basic entry under the ISBN and aim to be cheaper (or more collectible) than anyone else. The real benefit of Amzon over ebay is that it doesn’t cost to list & the listing stays active for 60(?) days and after that you can re-list if you want so it is all round less work. If/When a book sells they send you an email.

Just like round here, Amazon have re-vamped their site. One of the irritating things is they no longer include the buyers address in the email they send so you have to log on to get it. I suppose this is better from a security point of view, the less information in clear text mails the better. Not sure if this is why they have done it but maybe it does make sense.
