There is a holiday for everything, including T-Shirts. Since 2008, June 21'st has been "International T-Shirt day" and the day has caught the notice of our friends over at Game Day Depot. The Depot hosts many of the SBnation site's custom apparel stores, including Bull Run's store.
Since it's a special day Game Day Depot has decided to offer free shipping on Bull Run gear which is purchased on Tuesday, June 21st. You can get anything from our store including the "Football is Football" shirt, our "Back to Buffalo" Shirt, or any of our past designs (Fear the Mop, Release the Kracken, or I love NYBI"
You can also, of course, go with a plain white T-Shirt featuring the Bull Run logo to let people on Campus know the best site in existence for UB fans.
