Amazon and eBay are very different. EBay is better for collectibles, items limited in number (such as concert tickets), and used items. Amazon is better for media products (books, DVDs, etc), items new in the package, and toys.

The fee structure is completely different, too. Amazon does not charge up front to list your items. There is no Paypal on Amazon, so there is no such thing as an unpaid item. Amazon customers will pay more for the same items than eBay customers. To list an item on Amazon, all you need is the UPC code and the photo and description pop up – it is like a catalog.

EBay has a lot of hassles including many more restrictions, listing fees, and the Paypal system. You have to take your own pictures and write your own descriptions on eBay, which is very time consuming.

You should visit the seller discussion boards on both sites and understand how they are different before trying either one. Many sellers sell items on both sites.
