All summer, you can go to Sonic after 8pm and get 1/2 price shakes.
“Add-ins and fruit may cost extra.”
There are 25 flavors to choose from.
You don’t need a coupon.
I have a printed ad and looked on their website.
I don’t seen and ending date or when “summer ends.”
But, I’m guessing they will still call it summer for awhile! :)
