A few weeks ago Facebook developers introduced the ability to embed iframe applications (e.g., online storefronts) as tabs in user accounts next to “Wall”, “Photo”, “Discussions”, etc. This new feature allows shoppers to proceed to the storefront without leaving the online store’s main Facebook page.
