Here's why I don't like CL for anything but furniture, vehicles, & other stuff too big to ship. Too much hassle. This is the one that actually BOUGHT the phone, plus the hassle from the scammers & so forth that contact you but never buy.
You netted, what, $100 more than you would have from just clicking a few buttons on a web site and printing a shipping label? Plus you ended up giving your home address to some complete stranger, which would have been a deal-breaker for me.
The sites were offering $150, so I netted $150 of after-tax dollars, which ain't bad. But your point is well taken. It's a hassle and a risk, and not necessarily worth it.
