How does it work for you guys, what methods, apps, approaches are you using?

My interest there is twofolds:
  • as a merchant I am running online store where sell software so interesting to know best practices
  • I develop a Facebook app that helps (at least I believe that helps) to solve this problem, especially for fashion and furniture/homewares retailers, so wonder to understand how does it fit in


For a start of discussion, what do you think about having online store directly in a tab of your Facebook page? Does it work?
