I got this plugin a few days ago and assigned my programmer/webmaster to setup a facebook store for this site: http://medicalequipment-sales.net
First things first, it takes more than a few clicks to get this thing setup. additionally, it basically takes the pages from your site and displays them in an Iframe on Facebook. You still must setup the products, prices, etc this does not carry over. Also there is a huge limitation on shipping costs. you can only set one shipping cost. so if you ship a 700 lb bed or whatever and a 5 pd BipaP Machine both purchasers will get charged the same shipping.
Here is the real kiss of death, the darn thing does not display or would not display our products correctly.It would cut off the right side of the page and it cropped off the bottom part of the page as well.
I do not know if it was because of the theme that we are using on this site which I have grown to have less appreciation for. Of if it the plugin itself. We invvested 8 hours in trying to get this thing to work and then junked the whole project. I would be interested in hearing about the experience of others with this system. BTW if you visit the site, would you look across the bottom and share the site to your favoriate SM sites?
