When I saw the price of Arm & Hammer compared to Downy's Unstoppables, I had to try it. I figured that MAYBE there was baking soda in the product and that it could cut orders better....that was wishful thinking. There is no savings because the product does not work nearly as well thus more plus it takes a LOT more product so any savings has now been washed away:) The frangance smells fake and there is no defense/staying power to help prevent future odors. Downy unstoppables are by FAR a superior product.
Note, Downy is 0.60/oz and A&M 0.25/oz. The A&H I purchased is now being used in the garbage, heating vents, carpet before vacuuming etc. The chips do not last long but it is difficult to just throw it away.
Downy w/Frebreeze Odor Defense keeps clothing/linens from stinking up to a week (when used heavily) and up to 12 weeks when just hanging around.
