Step One - Sign Up For Cash4Books
Very simple. They pay you for books. This isn't the only step though. So sign up and come back here.
Step Two - Find Books
You can sell the books you own, but I like the books I have, so if I want to make money this way, I sell other people's books.
Go to your local library, used book store, Goodwill or other places where you find used books for cheap. You can also try garage sales. Write down titles that you find, or use your cell phone to visit Cash4Books.
Step Three - Buying Books
Use your phone to determine if Cash4Books will buy your book. If they will, compare it to the price you pay for the book. If you'll make money, buy the book and offer it to Cash4Books.
It's that simple. You will also learn what books sell well, and for what prices, as you go along. You'll be able to go out and pick out books that will sell quickly. If you have ever wanted to make money selling books, this is the easiest way I know of. I like it, I use it all the time. My local bookstore owners love me. :)
