Selling isn’t exactly free, as there are two main payment plans you can take advantage of depending on your selling style. These two plans are: the individual seller’s plan and the professional plan. The individual seller’s plan allows you to sell without having to pay a monthly fee, but taxes you about $1.50 per item that you sell. The professional plan grants you access to some of Amazon’s premiere seller’s tools, and doesn’t charge you per item sold, but it does cost you about $30 per month.
