I have been using PBS for about 3-4 years now. I have not purchased a single book for money during that time. I love reading, but I am not a fast reader, so being on a waitlist for a best seller is perfectly fine with me. I have saved tons of money by not buying books. (Libraries don't work for me because I am not good with keeping track of due dates and I feel pressured to finish a book since I may not be able to renew it when the time ends). This is a great site! No, not affiliated, just so grateful that I found this site years ago.
I currently have 47 of my books listed on PaperBackBookSwap. When I first began listing things would just fly out of the house, but apparently the books I have left are the lesser read books and they just sit there waiting and waiting for someone to choose them. So I have moved the stack into the closet so they don't take up visible space. I figure eventually someone will choose one, if I just wait long enough.
These are books that would lose me money if I listed them on Amazon, once Amazon had me pay their fee to them. But I'd still rather PPBS them than donate them to a library around here. I've heard of many libraries literally throwing books into the trash because they can't be bothered to even recycle them, and the thought bothers me. So I want to do my part to ensure they at least get to another reader.
I list books on paperbackswap for a month and if they don't go, I donate them. I don't want books in my house that are slow to move. I list books on Amazon for a year, then paperbackswap for a month and then they leave the house.
