I just recently did some spring cleaning and decided to unload a bunch of old books to make a few bucks. I look the book up on Amazon. You will find that some people sell books for as cheap as a penny. I am not sure why, but it definitely happens. If the lowest used price is worth my time, I then go to my Amazon seller account homepage you can open an account. Once logged in, you ueed get to your dashboard — see the image below…. Here, you can select the item type, but I mostly use the ISBN number — it is quicker and more accurate. Once you pull up your user item, Amazon will take you through a few more steps asking questions about your item. They will want to know…. Amazon charges lots of fees only on items that sell. This step is optional, but will definitely increase the chances that your books will sell and will help you sell them quicker.
