This add-on installs a oscommerce shop on a facebook business or private page. It is linked to the database of your existing shop and uses the same images as the OsC shop. No update is needed as it automatically updates when products, prices etc. are changed on your already running shop. I was not satisfied with Vendingbox or other modules so I tried myself. See our running example under:
( you see the shop-part under "Produkte", due to some facebook-bug or because the site has just been set up, it sometimes says "Page not found" but it is there, so try again later)
We do not actually use our oscommerce and facebook shop as an onlineshop but more as a product catalogue. But that should not make a difference as I just deleted products_price and buy_button. What I basically did was to upload a new OsComerce shop into a new folder on our existing shop directory on our webserver and installed this in a Facebook App. This application will be running in a facebook tab in an iframe. I am not a trained programmer or website developer, so this should not be to difficult.
