TULSA, Oklahoma - Boomtown Tees in Tulsa's Blue Dome District says they've sold out of their "Horns Down" t-shirts ahead of Saturday’s Big Twelve Championship between OU and Texas. But there's still a way for you to get one.

Just bring your own red or crimson shirt to Boomtown and they will print the design on it for free. The deadline is seven tonight.

 

It's limited to one t-shirt per customer, no hoodies or sweatshirts, and adult sizes only.
