Sonic Drive-In is offering 1/2 price Cheeseburgers every Tuesday evening for Family Night at participating restaurants!
According to the text I received from Sonic, the offer is valid from 5 pm to close on single-patty cheeseburgers only. Tax is not included and add-ons are extra. Let the server know that you would like the 1/2 price deal.
As always, this offer is for participating locations. You may want to call your Sonic to see if they are honoring this promotion before you head over there.
You can also score 1/2 price shakes and slushes after 8 PM every night.
