Participating Walgreens retail stores offer the Act II Microwave Popcorn (one bag) for 25 cents. (Check page 4 of your local ad to see this price.) That's a buck off and the best price we could find for this quantity of this popcorn. Sales tax is added where applicable. Deal ends June 23.
Planning on doing a major stock-up? This popcorn is also available online in Butter, Butter Lovers, and Movie Theater Butter flavors for the same price, and it ships free with an order of $25 or more. (Otherwise, shipping adds $5.49.) Note that Walgreens limits the quantity you can order for each flavor.
