Feeling sleepy? Well, even if you aren't, head over to Starbucks before 5 p.m. for the last day of their holiday special. From 2-5 p.m., if you buy one holiday drink, the second one comes free! Chipotle also has an ongoing buy-one-get-one-free sale if you check in at Chipotle on Facebook Places. Yeah, I know, holidays are awesome.
