Something in the latest X-Cart community newsletter caught my eye, and I’m not just talking about the questionable grammar. They were happy to announce launching a service to bring Products from an X-Cart store in to a Facebook tab. The service isn’t free, but (if it is easy to manage,) the benefit of being able to market products to all 500 million+ Facebook users, and link out to your eCommerce site, should more than pay for itsef.
