Tomorrow, May 28th, Baskin Robbins will be hosting their annual 31-cent scoop night. If you go to a participating shop between the hours of 5-10pm, you can get any flavor of ice cream for 31 cents a scoop.
They are limiting to three scoops per person, but 93 cents for a three scoop cup/cone is pretty awesome.
Here are more details on the event. You might want to call ahead and make sure that your local store is participating in the event.
