I was never in a frat, never had any custom shirts made - none of that stuff. So I'm not the target audience here. But they are one of the few places left to get Chief apparel. Namely, hoodies with enormous embroidered Chief patches front and center (although they sounded like a "when they're gone, they're gone" sort of deal, from what the girl tending shop said). Chief apparel of any sort is enough to make me a fan.
From what I can see, they don't carry a lot of licensed apparel, though - none of the Nike stuff, for certain, but I didn't even see a ton of "official NCAA merchandise" tags hanging around, so if you're looking for that sort of thing, you might be better at Gameday.
