To help this month’s Leaplings have a joyful birthday, Lay’s is “chipping” in on the celebrations that only happen once every four years.

A PSA for the approximately 200,000 Americans born on Leap Day: simply visit the Lay’s Facebook page on Friday, February 28, and comment on the brand’s Leap Day post to let Lay’s know that 2/29 is your birthday for a chance to win a free bag of Lay’s potato chips.
