You’ll love the current Hot Deals, sorry you missed this deal. This Thursday, June 18 Sonic is celebrating summer with 1/2 Price Shakes all day! Plus, don’t forget 1/2 price drinks from 2-4 pm everyday. What’s your favorite shake? My new favorite is Reese’s peanut butter cup! As always it’s a good idea to double check with your local SONIC Drive-In for participation.
