Amazon.com Informative - Never Sell Through Amazon!
SEATTLE, WASHINGTON -- Here's what I learned too late, and if you read some of the other reviews you'll see the same theme.
1) Whatever you sell on Amazon, you have to ship it out and wait at least 14 days before receiving payment.
2) Amazon gets a commission on your item, and if you want to get enough money to be able to pay the REAL shipping cost, you have to add that into your selling price so Amazon can get their commission on postage too.
3) If you're too broke to be able to spring for tracking, you may as well kiss your money goodbye, because the buyer can easily report that he/she never received the item and Amazon takes the money that was "in reserve" and returns it. You as the seller have no say in the matter.
4) Amazon makes a boatload of interest by holding onto money owed to sellers. Think about how much interest is earned in one week on $1000, and then use your best guess how many sellers are on Amazon. And if you've bought anything from Amazon, you know how fast that purchase is charged to your account.
5) Sellers should start a class action suit; buyers should kiss Amazon's ring.
