An image of the purchase stage of a MeCommerce block is available on right. I tried to post a demonstration, but could only get WordPress to display it in the sidebar and not in the post. To see a demo check out the MeCommerce site. The point is that each of those blue bars drops down when clicked to display all the fields you need to purchase. The initial display is made up of the front covers of selected books and CDs along with some explanation text. This purchase stage appears when an item is clicked.
MeCommerce is accepting requests for beta invitations, accounts will open on June 30th. I think this kind of revenue split and attractive functionality make a powerful combination.
