The donuts here are delicious! It's great that the shop is open 24 hours, because who knows when you're going to need that donut. Basically taste like Bosa. However, this morning was the first time that I visited the shop. I went there with a student coupon for six free donuts, and the cashier would not let me use it because the coupon was on my phone and not printed. Nowhere on the coupon or the ASU student insider website did specify that the coupon needed to be printed out. Personally, I don't see the difference, I guess it just makes them feel better to waste some paper.
