Through October 8 (or while supplies last), participating Starbucks locations will offer free pumpkin spice whipped cream on every pumpkin spice latte purchase in celebration of the PSL's 14th Birthday. (You can also request the topping on other beverages.) Introduced for last year's birthday, the topping is flavored with pumpkin, cinnamon, ginger, clove, and nutmeg.
