Costco May–June Coupon Book: Save Big on Tires, Supplements & Summer Gear
Costco’s latest coupon book is out, and if you’re a member, this is one you’ll want to flip through before your next run. The May–June coupon book runs from May 14 through June 8, which means you’ve got a solid window to stock up before summer kicks into full gear.
What’s in the Book?
Based on what Costco Insider is reporting, this round of savings covers a nice spread of categories that hit close to home for families heading into the warmer months:
- Michelin tires — Road trip season is right around the corner, and Michelin discounts at Costco are genuinely hard to beat. If your tires have been on your to-do list, this is the nudge to act.
- Orgain collagen peptides and milk protein — Costco regularly bundles bulk protein at a price that makes the gym membership look reasonable by comparison. Great for the household that goes through a tub a month.
- Canopies — Backyard cookouts, youth sports sidelines, farmers markets — a good canopy earns its keep all summer. Catching one at a coupon price makes the decision easy.
Who Should Pay Attention
This coupon book is a strong play for a few specific households:
Families with cars due for new tires — Michelin at Costco already prices well against Discount Tire and Walmart Auto. A coupon on top of that is real money saved, not coupon-book theater.
Health-conscious shoppers — If Orgain or similar protein supplements are already part of your routine, buying a warehouse-sized supply during a sale period cuts your per-serving cost significantly versus grocery store single-tubs.
Backyard entertainers and youth sports parents — Canopies tend to sell fast at Costco, especially once Memorial Day weekend approaches. Getting one now, on coupon, beats scrambling in late May.
A Few Things to Keep in Mind
Costco coupons are automatic at checkout — you don’t clip them or enter codes. Just shop as normal and the discount applies if the item is in the book. That said, a couple of caveats worth noting:
- Inventory varies by warehouse. Not every location stocks every coupon item. If you’re eyeing tires specifically, call ahead or check the Costco tire center directly.
- The book ends June 8. That’s not a lot of runway if you’re waiting on a paycheck or need to coordinate a tire appointment.
- Membership required. Costco coupons are member-only. If you’re not a member yet, the annual fee still needs to make sense for your household spend. [AFFILIATE:costco_membership]
Alternatives for Non-Members
If Costco membership isn’t in the cards right now, Orgain products are available through other retailers, and Michelin tires can be price-matched at several national chains. That said, the warehouse bundle pricing plus a coupon is typically tough to replicate piecemeal.
How to See the Full Coupon Book
The full coupon book is posted over at Costco Insider — it’s the fastest way to see every item before you make the trip. Worth a 2-minute scroll to flag what’s relevant to your household.
Bottom line: If you’ve got tires, supplements, or summer gear on the shopping list, the timing here works in your favor. The window is May 14–June 8, so don’t sit on it.
