I posted something earlier, but it never made it.
I am going to continue, probably $20 membership for unlimited swapping. For me, I’d rather swap, eventually get something I want (kind of like a surprise) or get it right away, than sell on amazon/ebay or just give to the Goodwill. I could give a ton of books away (I have a ton right now on PBS and waiting to be posted) but then I wouldn’t get anything in return. Even the tax deduction wouldn’t be much, if anything, and there’s no fun in that!
I have swapped so many books and have received countless (and in good shape), so I guess it’s been good for me. I also do amazon/abebooks and library sales (which I don’t do near as much as I did when we were building our library). I just picked up several at a library bookstore and many online in the past few days, along with PBS books. Fun, fun, fun!
