Arm & Hammer Pure Baking Soda in 8 oz boxes is plain sodium bicarbonate, sold here as a pack of 8 boxes (64 oz total). It is the standard pantry and household workhorse: leavening for baking, a mild abrasive cleaner, and a deodorizer for fridges, carpets and laundry. The pack format suits people who use it in several places at once. At $13.49 at Walmart as of November 7, 2026, that is about $1.69 per box, and only one store listed a new price, so there is no cheaper new option to compare against right now.
