What is the right platform for social commerce

selling products and services through social site is social commerce. Are you involves with social commerce, what platform do you use. I do social commerce mostly on Facebook. I use Facebook because it has a huge user base and I also have moderate number of followers.

I did try on Face Book joining a group but did not get any response. I noticed a specific product was advertised by most although the group was for a particular city for all products.
