I guess if you’re not sure what to price things for you can benefit from an auction format. But, I’m not a fan of the “deal or no deal” pages on fb. Most of the sellers know what they will take for something so why not just price it and be done with it instead of trying to milk a few bucks more out of it. Plus, if I see something I need I don’t want to watch a post for two days and make multiple offers for it. eBay isn’t what it used to be and by the time you pay all the fees you can take 25-30% less an just sell it outright. All of the above is why I have so much junk I don’t need setting around….
