I hosted one last weekend. If you're ever looking for the world's biggest cheapskate magnet, throw one yourself.
Seriously, this fat Asian guy with pock marked skin showed up and tried to buy two humidifiers for $5. I tried not to scoff at him but laughed my ass off as he drove away in his '99 Hyundai. Yes, they later sold for much more as did everything that the dickheads tried to buy for %90 off.
The Judy shall not be undervalued. EVER.
