$0.50 Corn Dogs at Sonic May 26You’ll love the current Hot Deals, sorry you missed this deal. Coming up Tuesday, May 26 Sonic is celebrating National End of School Day with $0.50 Corn Dogs all day! Plus, don’t forget 1/2 price drinks from 2-4 pm everyday. $0.50 corn dog day is one of the busiest days at my local Sonic. Will your kids be out of school yet? As always it’s a good idea to double check with your local SONIC Drive-In for participation.
