Where is the best place to own a sticky label public sale?
Answers: If you live in a populated area, I would simply have it at your home. You don't have to lug things to another location, and you can be home. In our area people merely put an ad in the report paper, or they just enjoy signs.
It depends what you are selling. If you were selling clothes, then see if you can rent out a space surrounded by your local shopping mall, or have other vendor join you at a church. If you were doing antiques or house hold items later a flee market. On the Internet I would try either eBay, amazon, or craigslist.org
Best of luck!
