There is a store here that buys and sells used books. I have used them.

I use a tablet and Libby for my books. I do not have to drive to the library. If I ever want reread a book, I just have to check it out again. Then the money to buy books, read it and then donate it. If I keep it, then I have to store something I may never pick up again.

I did buy books for my children. I did store them. When they had kids, I gave the books to them.
