Favorite Sites for Reselling

There are so many options out there for selling online. Ebay has been the standard for so long but there are up and comers like Etsy or Amazons Marketplace feature. I've also seen some people trying to sell via Facebook or other social media sites. Ebay is still getting the most views from potential buyers however, probably a strong alternative is quite a ways off perhaps because of how much Ebay caters to buyers rather than sellers.
