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.
I’ve had that happen too. But as I suspected is true in your case, I actually had a dialogue with the owners.
‘Course, if you didn’t know them, it could have been “hot”. I wonder if Craigslist, ebay or even the logal paper would be responsible for that. Or, more precicely, if any here thinks they SHOULD BE.
