The Publix Mystery Penny Item Is: Publix Brand Paper Towels (single roll)
Every Sunday and Monday Publix has an awesome Mystery Item that you get for a penny. For every $10 you spend (Before Coupons) you get a Mystery Item for a penny! You must use the Mystery Item Coupon that comes out in their ad.
Sorry, but Florida and Georgia Coastal Publix stores do not participate in the Penny Item promotion.
