We stopped by on our way to see my mother-in-law, used the coupon, got a dozen, a large coffee for me, some bagels for breakfast the next morning and a pound of Dunkin' Dounts brand coffee. 
I get the feeling that is the whole point of businesses making the coupons. You go in for a deal and end up buying a bunch of extra crap. Oh, sorry about the picture. Apparently, some people could not wait long enough for me to take a picture of the full dozen.
We go to the one on Military Drive near Lackland. It has been there forever (that I know of anyway). Honestly, how anyone could pick Kirspy Kreme over Dunkin' Dounts is beyond me.
