Selling used books online is one of the easiest, most fun, and most profitable part-time businesses out there. There is little guesswork when you use the tools that I'm about to show you, when deciding which books to buy for resale, and they are everywhere! For as little as 10 cents you can purchase a book that will resell for $ 4 – $ 100 or more on Amazon or other online selling sites.
When I first heard about selling used books online, it looked like it would be a big hassle. I figured you would have to list hundreds of books, not knowing what they were worth, and spend hours making an individual eBay-style listing for each one. Then ship dozens of books a day and only make a buck or two each. It did not sound too exciting.
