how to sell used things on amazon is a great way to declutter and make money online. Items such as books, DVDs, and electronics are commonly accepted in used condition. To begin, set up a seller account and list the items under existing ASINs, providing honest condition notes and photos. Competitive pricing is key, and shipping promptly will help you receive positive feedback. Selling used items can also help new sellers gain experience with Amazon’s system before investing in new inventory.
