You never know what you may find at the World's Largest Yard Sale if you go, but we know what you'll find if you don't go—nothing!

Yard sale hunting is something of a skilled sport: the best "athletes" go in with knowledge of what types of items could be worth something and search with determination until they find that diamond in the rough. Some like to just look around and see what kind of stuff other people hold onto in their homes.

If you put a little effort in, you can really end up with something valuable. One man, who calls himself "Garage Sale Coach," has basically made a career out of yard sale shopping and re-selling, and as he shows in his YouTube videos, he's making out pretty well. From just one weekend's trip, he made $1,400 in profit off of some old electronics. In another video, the coach made $1,500 in profit from selling old video game consoles, controllers and DVDs.

Check out the Garage Sale Coach's videos below, and get your shopping money ready for the World's Largest Yard Sale on Aug. 22 from 8 a.m. to 3 p.m. at the Saratoga County Fairgrounds!
