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

Is Zelle really safe? I read where the buyer could tell the bank the transaction wasn't authorized and that would be a chargeback with Zelle

Another option you can explore that I’ve taken advantage of is selling speakers through a local dealer who sells used and vintage equipment as well as new equipment.   That way, you can still put an ad online, but you don’t have to mess with the buyers. Also, people have the option to listen to the speakers, and it exposes the speakers to a wider audience.  They charge 10% commission but it’s worth it.  

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.
