If you live in the USA, you can find schedules of Public Library Book Sales near you here
Most of the books are donated and they are for sale between $.25 to $2.00. Most of them are still in good conditions.
You do not have to be a member of the library to buy books at the Book Sale. However, usually libraries give their members an opportunity to buy books first before other people who were not a member, on the first day of sale.
This kind of book sale is also a good venue if you want to recycle. You can donate your books that you dont need anymore for the sale. Usually libraries schedule a time for people who want to donate their books before the sale.
