Has anyone ever used YOONEW.COM to get cheap World Series and Super Bowl tickets?

Just wanted to see if anyone had used this site before, it looks like sort of a stock market for buying future tickets. I was thinking about buying Dodgers-Red Sox world series tickets, only $25 each to sit right behind home plate if they both make it. And if both teams keep winning the price will only skyrocket and I have the opportunity to sell if I want. Has anyone gotten tickets this way before?
