I sell a lot of bikes on cl, and I always price them. Some people just pay asking price, some negotiate. Most will say "what's the lowest you'll take?" Really? I put a price on it, now you want me to negotiate with myself???
Or sometimes they do make an offer but it's outrageous, like the guy that offered me $150 for a 5 speed Corvette. (I blocked his number)
Still others that do bother to negotiate either by phone or text, show up and offer less than agreed upon price. Or they make an offer by phone or text, I accept, then they think I'm gonna deliver it or meet somewhere. NO!!!
Some people show up when they say they will, and others not only can't keep their appointment, but they don't have the decency to call or text and say they changed their mind. I have other **** to do, and don't have time for people they say they'll be here at a certain time only to never hear from them again.
I've also bought a fair amount of bikes that were "make offer" and after looking at them in person and talking to the seller, a lot of times they'll put a price on it. Going in person makes a huge difference both in this case, and for negotiating if they do post an asking price.
My point is, selling anything on cl is a PITA. What works for some may not work for others.
Some of those bikes he'd be better off auctioning on ebay.
