How Does a Used Book Store Get All Those Books?

The answer is simple. One book at a time.
That's impossible you think. Well, it seems like it would be impossible, but every book on the shelf of any store has to be looked at by someone, and they have to decide if the item will fit into the inventory of the book store.
Whether it is a used college materials, collectible, rare, antiquarian or just general used books, the store owner has to stock them one at a time.
When a box of books come in they have to go through the entire box picking out what they want.. Sometimes the book store owner goes to a private residence to pick up new stock and will only pick out special selected materials.
Even when the car backs up to the store with ten boxes in the back and the owner sees a few interesting things, and they buy all the boxes at five dollars a box, they still have to go through all the material and pick out the ones they want, one item at time.
Enter the Book Scout. Help has finally arrived. This scout was an avid reader of science fiction and always ended up buying duplicate copies. Then he sold these copies off and realized there was money to be made. He started to buy up inventories and sell them.
The Scout was carrying a box and so the store owner is always excited to see this. Scouts sometimes come up with some pretty interesting copies as they dig around in the strangest of places.
The book seller ends up paying $60.00 for a stack and the Scout is off to another store to try and sell some more.
Book Scouts. The world needs more of them. There is cash to be made and lots of reading in the future. Pretty good part time / full time income.
