Facebook wouldnt work for my product range as my client base is from all over Australia and OS. Mainly middle age men who wouldnt look at facebook. Having said that, the wife listed a few music related items on facebook a couple of days ago.  This was our first try at facebook. It was easy to use and sold one item, paid full price and picked up within three hours. Several enquiries on some of the other items, so it looks very promising for some types of things. Retro vintage would probably work well as it would fit the facebook demographic of young trendies and middle age women well..
