Amazon has very high expectations for it's sellers. When you first start selling, if you sell more than 1 item a day you will get hit by a account review period of 21 days in which you cannot get any of your money but can still sell. If you get 1 Ding, negative feedback, or some cancelled orders, refunds, A to Z claims, you will be suspended and your funds will be available in 90 days. Even if you do manage to get an account going, you only get paid at the end of 14 days. And Amazon is much more competitive since everyone uses the same listing for an item. You are all competing for space in the selling box, and the lowest price or top rated seller is at the top. And you can't change the shipping price which is locked at $4.49 unless you have a business account, so you can't really sell anything below $4.5. Personally I think eBay is that much easier to use and sell, and they have more lax seller requirements. That's my 2 cents on the topic.
