Costco September 2017 Coupon Book Cover

At 22 pages this is a good sized Costco coupon book. We’re pretty excited to try a couple deals. We are big fans of Mochi Ice Cream, so will definitely be picking up some of that next week. Another item that stood out to us on coupon is the Korean BBQ Pork Jerky. Lastly, we love the Bai Antioxidant drinks, and may be purchasing multiple cases of that. We bought the Hansgrohe Talis M Pull-Down Faucet last time it was on coupon and have been extremely happy with it. Costco Insider highly recommends you buy it if you’re in the market for a kitchen sink faucet. The tire coupon is Michelin again, just as we predicted.

If you’re still looking for the September 2017 Costco Coupon Book then scroll all the way up to the top and click the link in the very first sentence when you’re on the September 2017 Costco Coupon Book page. We’ll also be posting the in-store pricing after coupon very shortly, so check back for that. What are your favorite coupons this month? What will you be buying in September?

      If you purchased the items at high price within a certain period of time of them going on sale, just bring your receipt to Costco and they will refund the balance. Easy Peasy.

      • Yaya

        Do you even need the receipt? They know exactly what you purchased.

  • Greg

    Nothing here worth one’s time. More pleased than ever that we dumped Costco and its higher fee.

    • Pamela Roblyer

      Then why are you still reading the Costco Insider?

      • Greg

        Who, but you, said I was reading the costco insider?

        Mind your own business.

            More Truth

          • Jennifer Sanchez

            I’m sorry about whatever in your life has made you so angry as to blow up at strangers over the comments section of a Costco sales ad.

    once upon a time, they’d often put the whole, raw chickens on sale BOGO. I’d get a bunch of them. They were kind of small, but grilled up nicely. Those were the days.

    Went there to get paper products last night.

    Noticed that some of the snack items like box of 24 cup of noodles and 72 bagel bites come back frequently on unannounced markdowns, It’s about the third or fourth time for each this year. It might be good for a poor student to stock up on. Each ramen cup works out to less than 20 cents.

    They brought back the Nong-shim instant udon bowls but haven’t put them on markdowns yet.

    The stores here feature Chinese, Korean, or Japanese products.

    If you download the Costco app to your phone then you can have the same coupons. I thought this site has some sort of Costco coupon prediction or something similar concept.

  • Joseph Hamilton Hoffman

    Always the same products, month after month, nothing new. What happens to this marketing guy!!!
