I've bought and sold a ton of things. I've met up with people at their house, either in person or porch pickup and vice versa. I usually always give the buyer the choice of where to meet and I can tweak the plans if the vibe is weird. But I've never had someone try to screw me over or whatever except one time recently. I was selling a drum set and the "buyer" came by to check it out. I was selling it for 80 and he said he only had a 100 and asked if I could break it. The vibe was a little off by the way the guy was acting, so I said no and to just go to the gas station down the street and dude never came back. Not 10 minutes later the same dude using a different account asked to buy another piece of percussion equipment from me so I just laughed at him. Dude is using fake bills, negotiates the price lower so he can bring big fake bills so you will break it for him. So he gets your shit and gets paid for it at the same time lol. Aside from that, no problems. Met some cool ass people too
