I have used Craigslist, I also wouldn't for one second think about showing up at a person's house un-announced and start ransacking their place. But then again I don't have a felonious personality either.
I remember a very old saying, "If it looks too good to be true, it probably isn't."
I just bought a $2,000 love seat, used less than 1 month for $150.
Looked too good to be true to me.
Turned out I knew the sellers, legit sale, they just didn’t want it anymore.
