Have you ever gone to Craigslist and just clicked around?  There is some fun stuff for sale, along with a few other fun things!  If you click on Craigslist you never know what you might find, of course there are the usual items like cars, home goods, and other items you might use around the house.  Then there is the odd Halloween costume like the one that you can pick up because the owner feels that it's not cool to wear the same costume two years in a row.
