Received a "We Miss You!" email from Papa Murphys that contained the below 50% off coupon for 1 pizza, and I am guessing it is multiuse (I already ordered/paid for my pizza). Let me know if you have any luck - I am in MN if that has any impact at all. I ordered a family specialty pizza and it knocked it down to $8 from $16.
