At every Sprinkles bakery location tomorrow, customers will be able to get a free cupcake with their cupcake purchase, according to the brand. 

If you're interested in taking advantage of this tantalizing deal, all you have to do is whisper "chocolicious" at checkout. After mentioning said "password," you will be able to request any cupcake flavor of equal or lesser value. Keep in mind, however, that there is a limit of one per customer.
