Costco May 2026 Coupon Book

May Deals are Here – With Memorial Day Weekend in the Crosshairs!

The April book wrapped up on May 3rd, and after a full week off (officially back the new normal at this point), the May 2026 coupon book takes the wheel from May 11th through June 7th. That’s a healthy four-week run, with Memorial Day weekend tucked right in the middle.

Speaking of Memorial Day – mark your calendar: Costco will be closed Monday, May 25th in observance of the holiday. So plan your hot dog and burger run accordingly. (Or grab the Kirkland Signature Crispy Wings featured on the back cover for $14.99 and call it a day.)

This month leans hard into summer prep. Window AC units, portable AC units, fans, sunscreen, bug traps, pool shock, patio furniture, and a whole lot of outdoor cooking gear. There’s also a serious appliance push happening, with LG, Whirlpool, and Samsung all running save-up-to-$1,700 events at the same time. If you’ve been putting off a fridge or laundry upgrade, this is your window.

May is also National Dental Health Month, which means the Crest and Oral-B page is loaded – the Oral-B iO Electric Toothbrush 2-pack is $30 off, which is one of the better deals we’ve seen on it.
