Library Book Sale

My town's library has a book sale twice a year. Tonight in four hours we made $ 3500.00. I volunteered to help out. I also had first crack at the books. I went for religion and poetry. Some people bought boxes worth of books. Hardcover books are $ 1.00 and softcovers are $.50. I think some people went for old books just to resell them on ebay or craig's list. It was fun but tiring.
