ScreenUsed.com will be selling off a ton of very cool movie and TV props online July 6. If you want to be the most authentic cosplayer at Comic-Com this year, this is the easiest (if not the cheapest) way to do it! You can buy authentic costumes worn and props used in Buffy, Star Trek, Blade, V, and tons of other films. They give an estimate as to how much they feel some of the items will sell for and there looks like there is a price range for all wallets.
Check out just a few of the awesome goodies up for bid:
