Zapper is easy: type in your barcode/ISBN numbers & see what they will pay, then when you have finished your list, print off the postage label, package up your books, stick on the label & take the box to the Post Office (unless it's a huge package in which case they will send a courier for it!). Get a proof of postage receipt just in case, then wait for an email telling you a cheque will soon be in the post. i have used Zapper twice now and wish I had heard of them earlier. Highly recommended by me!
