some people say fb marketplace is sketchy but I am constantly surprised by how nice and anti-scammy my neighbors are
once sold someone a nice backpack and didn't realize there was $20 in a pocket
they came back to give me the $20
today I sold one of my manual espresso makers, the guy paid in cash, and he accidentally shorted me $10
he realized this HOURS later while doing laundry and is insistent on dropping the $10 bill off with the leasing office while I'm out tomorrow
