Amazon -- Earn cash by selling your stuff on Amazon.com. It's easy, it's fast, and it doesn't cost you a penny until your item sells. Amazon is becoming the site of choice for many online sellers, especially those no longer satisfied with the direction eBay has been going.
Amazon has long been known as a big place that sells stuff but now you can sell your stuff there too. There is a completely different philosophy and, therefore, a different set of rules, than eBay and many people like this. Be sure you check the rules out first before signing up for an account. Amazon may not offer what you are looking for.
Form many others, however, Amazon has been exactly the change they are looking for. It has a powerful payment process or it's own and sends payments (less their fees, of course) directly to your registered bank account.
Shoppers see the familiar, powerful, and comfortable, Amazon shopping cart and can mix your products right along with regular Amazon products and other sellers' wares. It's a dream to use.
Books may be the best product line to start with but there are many other possibilities too. Some items are not allowed and Amazon puts conditions and limitations on the ones that are but once you are familiar with these, and the easy listing process, you may find that Amazon is the only selling venue you need.
It is certainly worth a look.
