I'm just amazed at the number and quality of books that are passed on to me to sell and raise funds for school. I'd love to have time to read a many of them, but.......!
As gate sales don't keep pace with the number of books that I receive, I now sell on Amazon and Green Metropolis.
Just before Christmas I discovered Ziffit.com, which is similar to Amazon's "Trade in" site.
A fast and efficient service and great if you have a lot of books to sell.
