The upcoming August 2017 Costco Coupon Book will run from August 3rd through August 27th. The July 2017 Costco Coupon Book ends on July 23rd, which will leave 1.5 weeks between Costco coupon books, which is a pretty standard time between coupon books. I posted many of the upcoming dates for the Costco coupon books on my page Changes to the Costco Coupon Book – Part 2, so check it out if you want to see more dates for the upcoming Costco coupon books.
