The January 2026 Costco Coupon Book is traditionally heavy on New Years Goals/Resolutions helpers. This year is no different with all the weight loss, supplement, protein powders and more. Our favorite protein company is Orgain with their organic and all natural products. The 30g Milk Protein Shake is great if you’re going to the gym and trying to feed those gains with a quick ready to drink shake. Their new Micronized Creatine Monohydrate Powder is fantastic too. We tried it recently and were very impressed with how easy it is to get a reliable does of creatine without added ingredients. Huggies don’t go on sale too often, so now is a good time to stock up on those too. This months tire coupon is back to Michelin with $80 off any set of 4 tires.
