Half-Price Shakes at Sonic on St. Patrick's Day

In case you don't want to wait until 8 PM to get a half-priced shake, Sonic will be offering their entire shake selection for half the normal price all day on St. Patrick's Day at participating Sonic locations.

Unlike recent deals from the chain, it doesn't look like you have to mention this one when ordering (although it couldn't hurt). The deal is good this Thursday, March 17, 2016 only but they're also offering half-price shakes after 8 PM through the end of summer.

Sonic's current shake menu boasts 23 different shakes and includes new Creamery Shakes.
