I do see PSL's on eBay all the time. They're just trying to skip the fee on the other official websites and get more eyes on their sale. But wherever the PSL is sold, the transfer has to be executed though the Cowboys office and they use the STR marketplace.
Lots of fans saying that there's no home field advantage, yet say they'd never go to the game due to (rather watch from home, hate the stadium, hate Jerry, cost, etc). As the other poster said, we go for the team, the friends, the memories. I do wish we were winning more, because it does cure all!
