This month at Costco there are some great deals using the following coupons! Prices are valid 9/4 – 9/28, unless otherwise noted. Costco is a membership clubhouse, so you must be a member to use the coupons. The coupons in the booklet are manufacturer coupons. When redeemed, state sales tax may be due on the value of the pre-discounted price. These taxes, if applicable, are in addition to the amount that you are paying for the product. Selection may vary by location. The instant savings booklet offers are manufacturer coupons, valid in U.S. Costco warehouses and not valid at Costco Business Centers. They may not be combined with any other offer or coupon. Selection and pricing may vary. A rain check may be issued if the promotional item is out of stock during the term of promotion.
