This is how it works. When you join you are given a few free credits to start. You can add to those credits by selling your own books. Their system to sell your books is very easy. You just enter the ISBN and it will bring up a picture of your book immediately. They will ask if the book is in good selling condition and that's it. Once someone requests your book you are given a certain amount of time to mail it. Once the book is received they will go to the website and mark that it's been received. That is when you receive your credit. Now you're ready to purchase a book with your credit. You receive 1 credit for each book or 2 credits for audio books.
It costs approximately $2.30 to mail a book using book rate so any book I choose through PS will end up only costing me that amount.
I have ordered a lot of books through PaperbackSwap over the past 5 years or so. I've never had a bad experience. In fact this past month I received The Five Silent Years (about Corrie Ten Boon's last 5 years), Chicken Soup for Caregivers and the audio tapes for Pilgrim's Progress. Of course they do not have the newest books available so I put those on my Wish List. If the book becomes available then I am immediately notified before it's listed to the public.
Do you have a favorite used book club? How do you support your book habit?
