Sonic 1/2 Price Cheeseburgers ThursdayYou’ve missed this freebie, but you’ll find all of the Freebies hereKick off the new school year with 1/2 price Sonic cheeseburgers all day on August 14th. How do you like to personalize your Sonic Cheeseburger? My favorite is ketchup and mayo but no tomato. Plus, don’t forget about 1/2 price drinks from 2-4 pm daily! Check with your local SONIC Drive-In for participation.
