I like Etsy because it targets an specific market, I could link it to the blog, my facebook page and twitter. Also, when people check out from Etsy they could use their Paypal account or they could just pay through the etsy cart. I don't have to worry about calculating shipping and I could sell everywhere in the USA and outside as well. But, I am still researching because all those options have their pros and cons.
I voted for Facebook, but I'm not really sure it's the best site for this. One key factor I think we need to know is who charges the least? I have heard that ebay charges the vendors a lot. We need to look at the costs.
