Well here is one little positive in regards to tax day. On April 15th Sonic will be offering their happy hour all day long [2] which means 1/2 priced drinks and slushes!
Just a little fun fact…according to Sonic they offer 1,063,953 drink combinations. Now that’s a lot of options!
As always, it never hurts to call ahead just to verify that your local Sonic is participating in this deal.
