Finding Inventory

All dealers get books in the same places… walk-in traffic, garage sales, Goodwill stores, Salvation Army stores, church sales, library sales, estate auctions, newspaper ads, scouts, other bookstores, remainder outlets, etc. Pay more for fewer but better books. You are competing for those higher quality books.

Supply and demand
The biggest problem that your online bookstore faces is the fact that you can’t easily apply standard retail wisdom. Books on retailing will tell you that you can go for volume with low prices, or go for service with high prices.

Set your prices high enough on your decent books. Remember that your supply is limited. It’s easy to get a lot of low quality books in your inventory. But it’s difficult to maintain a stock of really good books.
