nice website you got there Therese!
Yes I agree with Suzy that the best way to sell on Facebook is not to sell. Facebook is about creating a personality and showing that there are real and genuine people behind your company who speak with an authentic voice.
For instance, you can check out the Walmart and Target Facebook pages, although these are the very definition of giant multi-national corporations they come across as pretty folksy and personal. Other good ones to check out are Converse and Vans Sneakers, they have very cool pages. My favourite could well be Mophie's Facebook page (they sell iphone battery pack cases), I think they hit the right tone for a Facebook page that remains interesting and informative without being overly salesy.
