Yardsailing is the act of driving around town searching for yard sales.

Yardsailing is usually done by people who buy random things for a cheap price and sell on eBay for way more than what it's worth.

Yardsailing is also practiced by people who enjoy going to yard sales for the fun of it.

A person who goes yardsailing is known as a yardsailor. Yardsailors typically wake up early, search newspaper adds, and stay out till every last yard sale has been sailed.

Yardsailors are not to be confused with passerby's who stop at a yard sale just to have a look.
