I just spent 3 hours this afternoon selling (or trying to sell) my paperback fiction books. My son decided he wanted to sell some of his books as well. He ended up playing at the park with Dad, while I manned the table. So for my first time out as a book seller, I sold exactly 5 of my books, and 2 of my sons - and made $3.00 total.
We just set a table up outside on the street. I wasn't too fussy about the prices - it's more important that I get rid of them as I have too many books. I was charging 50 cents for my books, and a quarter for the kids books.
Next time I think I will have more hard back books (going for $1) and more non-fiction books. Actually I enjoyed myself, just being able to sit in the sun (wearing a cap and suntan lotion) and reading a cheap novel.
