I like the plugin. By looking at the screen shots and demo , I can say that it is an excellent one. I can say it is better than WP E-commerce and eshop. Both of them create automated pages.But they are not well designed.
The third one I like is Zingiri web shop. But it doesn't support Multisite environment .
JogoShop looks advanced. But I would like to suggest that currently...the 1-click add to card feature is Ok. But the pages are refreshing every time we add a product to cart on order page. It doesn't happen with other plugins. I hope you would look at this issue
