iStalls is a combination of a web store and blogging platform. You can create your own web store - or a recommendation service/blog in the shape of a web store - with just a few clicks, as simple as a post on Facebook. Fill it up with links to the goods that are sold in other stores.
You can create a web store of anything you like, and you can also sell your own goods. Also you can earn money by subscribing to an affiliate program of some web store and promoting its goods.
