The May book wraps up today (June 7th), and after the now-standard week off, the June and July 2026 coupon book takes the wheel from June 15th through July 19th. That's a five-week run, which is a little longer than usual, and it carries us right through Independence Day.

This book goes all-in on summer. Sunscreen, hydration mixes, Bluetooth speakers, coolers, luggage, and a stack of outdoor-friendly gear. There's also a big online appliance event running with LG going up to $1,800 off and a Costco Direct "buy more, save more" stack on top of that.

Looks like Costco Insider beat the mail truck again, with the complete book ready to browse today👇👇

Thousands of unadvertised deals from Costco stores around the country. New deals added daily.
