Inventory Source gives you the tools to find and manage multiple wholesale suppliers, manage multiple websites, sell hundreds of thousands of products, work with online auctions and marketing channels, and is a 100% automated solution.
I replied to a similar post a few weeks ago about inventory source. Here's the link to the post:

My shop kart gives you a fully functional web store. They host your website but you are in full control of it. Easy to use website utilities allow you to manage all the products you sell. There is also a comprehensive help system which will guide you through the setup & use of your store. To learn more about them, please visit this link: Link hidden: Login to view (if you haven't already).
Personally, I haven't used both sites. But they are quite different from each other. If your looking for a ready website which you can use within 5 minutes then go for myshopkart.com but if you're more into drop shipping and need help monitoring your stocks then inventorysource.com is the one for you. But if you remain unsure, might I suggest that you start out with a sites that do not require any fees to set up your store, like eCrater for instance.
If we have any members with first hand experience on any of the sites mentioned your inputs will be highly valued.
