Can you be a bit more specific? Is it something you make? Some people set up facebook pages with their own little boutiques. Some use http://www.etsy.com/ where you can sell anything handcrafted. What are you selling?
What kind of products do you sell ? Try : Zibbet.com artfire.com shophandmade.com Good luck and hope sell a lot ..
Add me to the list of happy Etsy sellers. The etsy staff and the other sellers and buyers on it are just amazing. Another marketplace I use to sell my stuff is ListingDock.com, great place to buy/sell/trade with ease. The website is easy to navigate and when I have questions the help desk is very helpful.
