The March 2026 Costco Coupon Book seems to focus on spring season. There are several outdoor yard items on sale, whether it’s the Fiskers Pruner and PowerGear Lopper Set for $5 off or the variety of Scotts Lawn Weed & Feed, Max Lawn Food, Max Grass Seed, or Miracle-Gro. Now is the ideal time to use all of these items, so it makes sense that they’re featured and on sale. One of the items that stood out to us is the Ninja Crispi 5-in-1 Portable Glass Air Fry Cooking System. Using glass for your air fryer is healthier and non-toxic. At $35 off, this could be a great time to try one out! We also love the Blueland Dishwasher Detergent Tablets and will be taking advantage of the $5 off. The tire coupon this month is Bridgestone with $80 off any set of 4 Bridgestone tires.
