You guys can all offer but I am the only one with a proven track record of returning the funds after the match. Also, it only works if you are the victor as I assume Girly wouldn't let a person transfer their G's after they have been selected for elimination.
I would be suspicious that Rathji would keep the whole amount and deny the deal. And, can you really trust the lowest bidder? HockeyGuy probably offers such low prices because he doesn't secure the funds. Or he loans them out to other people for wagers.
