Starting a sellers account on Amazon is incredibly simple. However there are a few things you should think about before you start. The first is "Do I want a Professional account or not?" It breaks down pretty simply If you think you are going to sell more than 40 items a month then a professional seller account is the way to go. Also if you think you want to sell items in "Gated" categories then you would also want to have a professional sellers account. A "Gated" category is a category on Amazon that requires additional permission to sell in. These are categories that have expiration dates, that require special photography, that are easily and/or often counterfeited or are sensitive in nature. Some of these categories are Clothing, DVD's, Collectable Books, Health and Beauty, Groceries, automotive and more.
