Type a physical letter, give it to your store manager, then on the same day send that letter slightly reformatted as an email to give your management a digital record to refer to.
This will help everyone cover their asses. Yours because there is both a physical and digital record so in case one gets lost there is a backup. The store gets covered because they have a physical and digital source to use for finding coverage and changing availabilities.
Edited to add: the professionalism answer is two weeks, but your physical and mental health is yours and yours alone, so I can't really answer as to whether it is smarter for you personally to quit immediately or to give 2 weeks.
