There are some great deals in the October 2025 Costco Coupon Book! First of all, with our kids being in the heart of soccer season, it’s a great time to stock up on their favorite — Orgain Kids Nutritional Protein Shake Chocolate at $9 off. We love that it’s ready to drink and they can have it right after the game to fuel those muscles! We also are big fans of their Plant-Based Ready to Drink Protein Shakes, which are $7 off. Kirkland Signature Diapers aren’t on sale too often, so picking them up while they’re on sale at $14.99 – $39.99 depending on size makes a lot of sense. We also love the POM Wonderful 100% Pomegranate Juice at $3 off on top of Costco’s already great price. This months tire coupon is Michelin at $40 off a set of 4 totaling $798.99 or less and $60 off a set of 4 totaling $799 or more.
