I agree with you with regard to "making money" at a yard sale. The reason I'll hold a garage sale is to get rid of stuff, and I tend to sell everything at a major discount, and even give stuff away.

Unlike you, however, I enjoy spending a few hours on a Saturday morning going "yard saling." Whenever I visit my family in Ontario, my siblings and in-laws and I inevitably schedule one Sat morn for a convoy (comprising 2-3 cars) going from sale to sale.

If we don't find any bargains, we're sure to find some interesting crap.
