Used books

Besides selling my handmade clothing online, I think next time I also can sell used books. My house have lot of books for the girls. I just love to buy or subscribe books for them after both of the enter school. I am glad that nowadays they have developed reading habit whenever they are free. However lately I noticed the book shelf is too packed with books. It's time to spring clean them and sell them if possible. So that I can slot in new books in future.
