Many Costco members are saying the May 2026 Costco Coupon Book is the best one this year. It’s definitely a matter of opinion and whether the items on sale are what you usually buy. For example, are you a Charmin Ultra toilet paper family or a Kirkland Signature toilet paper family? If you prefer Charmin, you’ll be very happy with the $6.60 off this month. The adidas Cloudfoam Flex Sneakers are well liked by those who have tried them, and are $7 off right now. Spindrift Sparkling Waters are $5.20 off a pack of 30. The new Once Upon a Farm Immunity Blend variety pack are $6 off, and since we haven’t’ tried them yet we’ll need to give it a go while on sale! This months tire coupon is $80 off any set of 4 Michelin tires.
