Just noticed this day's offers on Craigslist... Wonder how many people will want to buy at these prices..
When I saw the title of your thread, my immediate reaction was to ask you how much you would pay me to take them off your hands.
Two places I have seen often are the lobby of the local police department and a bank lobby. I once (what was I thinking) met a guy at a Subway Sandwich Shop (really sketchy guy...would never do it again).
I recently did a CL deal, the post said meet at police station, but inclement weather on that day, and next day was a coin show, so we met there. Went well. Of course I was carrying, but nothing even close to sketchy.
