Recently, Amazon announced their Webstores. These are fixed URL websites that you can set up and sell products from, just like any website. You would supply your own URL and choose from any number of templates that Amazon offers. Amazon acts as the web host and the payment processor in this arrangement. You get a built-in shopping cart and payment gateway as well.
These stores go for about $60 per month and the per-transaction fee is 7%. That’s pretty comparable to eBay stores, so it appears that Amazon might be going after frustrated eBay store owners who are looking to migrate to other venues.
One major advantage to these stores is that you get integration with Amazon. You can place anything that Amazon sells on the site and use your Amazon affiliate account to sell those products. That is great for testing products or Adwords campaigns.
Amazon also integrates their search engine and their review system into your webstore. You also get Amazon’s descriptions on affiliate products you place in the webstore, although you are able to override those and put in your own.
Downsides: Shared IP addresses I believe. Also you don’t get any traffic from Amazon search (in case you were thinking “oh boy free traffic!”). You will get an index link from your seller panel in Amazon. That’s very similar to the way eBay Stores work. You can link to them from your MyWorld or About Me but that doesn’t get you much traffic.
If you’re looking for an affiliate host for Amazon products however, this is a pretty good arrangement. You read more about the Amazon Webstores on their information page as well as see some actual sample stores (link here).
