For in-store pickup only and with stock varying by ZIP code, Sears offers Shop Your Way Rewards members the Morton System Saver II Water Softening Salt Pellets 40-lb. Bag, model no. 1500, for $4.49. (Not a member? It's free to join.) That's about $2 under what you'd pay in-store elsewhere, although we saw it for a buck less in December. These pellets purportedly reduce scale build-up in showers and bathtubs and extend your water softener’s life.

Of note, Shop Your Way Rewards members may be eligible for additional credits and discounts.
