Sonic: Half-Price Shakes All Day on June 20, 2012
Mark your calendars!
Sonic is offering Half-Price Shakes All Day on June 20, 2012 (the “longest” day of the year and the first day of summer!).
They say that this is only at participating locations and hours may vary, so I’d recommend calling your store ahead of time to verify that they are participating in this all day long.
