I'm not sure where this should really go, but I had to pick a place, so here it is. I listed my Polk REi 38s and CSi 30 on what I thought was the local, i. e., SE Michigan Craigslist. I just got a text from a Los Angeles, CA area code offering to send me a check and have someone pick up the speakers AFTER the check clears. Now this came at 11:30 PM or so EST, or a few minutes ago. I know that's 8:30 PM in L.A.. I did not anticipate this. I was expecting local interest. It seems like this party is willing to invest much more than my asking price for these speakers. I can't understand how this party would trust me. I'm also sure that there a million ways this could blow up in my face. Thank you in advance for your insights.
