With the vernal equinox Friday marking the official start to spring, it’s time to celebrate.

The Campus Bookstore is offering a BOGO sale on T-shirts, Thursday and Friday, March 19 and 20. Buy one full-price T-shirt and get a second of equal or lesser for half price.

“It’s a great way to observe the arrival of the warmer weather,” says marketing coordinator Martin Deck. “Save on a couple of T-shirts. Wear both yourself, or split your purchase with a friend.”

The sale does not extend to the Win City apparel line designed by BB Branded.
