CL is a virtual garage sale.
Accordingly, from the buyer's perspective, expect to rummage through tons of junk to find anything at all that you might consider taking home, even it were free. From the seller's perspective, expect to find buyers who will intentionally waste your time and then to low ball you.
This is what a garage sale is all about.
If you have the time and the patience and a little bit of forbearance for your fellow man, it can be quite fun and rewarding.
