Atlantic Superstore Grand Falls NB flyer for Madawaska Road 240, ch. Madawaska, Grand Falls, New Brunswick (NB). Biggest variety of food, beauty supplies, baby items, Pharmacy. Everything you would need Even clothes but selection of food is the best.This store is always clean, organized, well stocked, lots of variety, organics, plants, flowers, deli, bakery, clothes, pharmacy, household items and more. I find them expensive, but with the overhead costs, it's almost understandable. They do feature great sales and seasonal clearances. Spacious parking, clean restrooms.
