I made about $600 over one summer by visiting garage sales and selling items on eBay, as well as weeding out some stuff I didn't need (and haven't missed). I really loved it because it was so much fun to get something that probably would have been thrown away or unappreciated to be in the hands of a loving collector!

Sell something that you know. For me, it was books (mostly nonfiction) and video games. I had a pretty good idea of value but there was always some risk.

My mom also made a killing selling old Halloween costumes she had made on eBay. At a garage sale we would have practically given them away.

Before you go whole hog, try eBay out as a seller and get to know the process. Half.com is also good (not an auction site) - you don't pay a fee until an item sells. Half.com is now owned by eBay too.
