JFBConnect doesn't automatically add the Like button to your pages, but it's very easy to add it to the flypage template in Virtuemart. With a few of our tags {JFBCLike} and {JFBCGraph} you can easily add the Like button as well as describe the product so that when it's Like'd, the right information (image, title, link) show up in the user's wall.
We can help you implement everything should you have any questions.
