Selling towers - keep getting bad actors/scammers when doing local pickup only.

I too have heard about bad things with Zelle and some of these other bank to bank transfers, wire transfers are safest. Cash is king, counterfeit bills, carrying a lot of cash could be issues. Can't believe people aren't mentioning issues dealing with mountains of scammers, yeah, their mostly just pests if you're familiar with selling on web, but they never cease to bother. Tire kickers another form of pest, some of these are complete phonies, trying to see if you have other items worth coming back to steal. I know any number of people who now refuse to sell on these platforms since they're rife with scammers. At this very moment I have old riding lawn mower for sale on Facebook, there are scammers even for this $250 old dog. Gave up practically trying to give away tons of old audio magazines, only bites were fake Facebook entities inquiring about audio equipment I may have. I gave up tossed all the mags in garbage.

If it's big and heavy enough, I always do local pickup; sold speakers and amps that way through Agon or USAM, the buyer came by with cash, we did the transaction, and everybody was happy. It takes longer to sell, of course, but it's worth it to me to not have to deal with shipping these things. 

Like @viridian I've never had a bad experience with craigslist. The worse it gets is those folks who insist on meeting in a supermarket parking lot, which is really annoying because you can't test the gear. But then again that lets you make a significantly lower offer on the item because, well, you can't test it.

From what I've heard though, the craigslist experience varies greatly from region to region. Around here it's pretty great, but one time I sold a truck to a guy who had just moved to town who, as soon as we were done, started gushing about how pleased he was with the transaction and what a great seller I was... To me it had been a pretty normal transaction, definitely nothing special, so I asked what do you mean, and he explained that in NJ craigslist is unsafe, you never go alone to a meetup if you carry cash, etc. Which explained to two guys he'd brought along I guess 😂

Occasionally you'll see some pretty high end components on local craigslist, up to $10K or so sometimes. 

I listed LRS + on a site and I had interested parties but they were giving me flack for wanting cash. $850 is NOT a crazy amount of cash to carry. I paid cash for them and that’s how they will be sold. You’re coming to my house to get them. What are people worried about? I took them offline after 2 guys wouldn’t pay cash. I put the speakers downstairs in the basement. I don’t need them gone that badly.

I have a suggestion. You can ship large items without having to package them using an independent LTL Shipper. You'll get a much better price for your speakers if you can open it up nation-wide.

Several years ago I shipped a large item to big to pack using one of the sites where you ask for quotes. Sorry, it was a while back so I don't remember which one, but there are several to choose from like uShip, Shiply, etc. I found a guy who was already going past me, and my destination, on an upcoming trip. He just bungeed it inside his box trailer and charged me way less than what you would pay to ship via UPS!

Good luck!
