Yeah, when I was moving and held a garage sale -- these people show up at 7 AM while I'm still in me jams and thinking about breakfast. My sister says, "There's people all over the driveway!" Stupidly I opened up and didn't get a break for about 3 hours.
What unnerved me the most was people offering half or 1/4 what I listed (and thought of as a bargain price) on a vintage gumball machine, right off! No. Not gonna happen.
You could sell right off, have some money in your hand. But what's the rush?
