I haven't bought anything off of CL in years, but I do try and sell stuff all the time, I only list my phone number ( spelled out) as I get to many wasted Emails ( 99.9% scammers fishing ), if you really want my item then you will call and talk to me, but I still get a lot of flakes calling. I also won't give my address until you are ready to come & look at said item. I very rarely get a reply when I see something of interest & Email about it so I try to look for stuff that has a phone number. From where I live most bikes that are for sale on CL are 2 to 3hrs away, I don't think many people in our county know about CL ,& most that do are selling antiques not bicycles.
