That one's expensive because it's a customizable one. I'm not sure where you live, but you can always get one at the stadium if it comes to that. If that's too expensive, you can always wait until he leaves us and get 4 for $20 at a tent sale at the stadium.
I got a Dye T-shirt jersey and a shirt that says "Cowboy This" from the 2003 playoffs with Boston for $10 at one of those. Hopefully we won't be seeing Chavvy ones there for a while.
I did a quick search though, and I only found customizable ones too.
