Do Fans Actually Buy These?

 

I say this not as an umbrage to Chris Weidman, or any fighter, but simply as an honest question.

I don't know that any of the guys I train with own any walk out t-shirts, well, maybe I've seen one person wear one to the gym one time.

Thoughts?
Btw, I'll take any lack of commenting/silence to mean that no, in fact, no one buys walkout t-shirts.
