All discounts have already been applied to the listed price and you can find them all in this coupon book, so need to hunt for a coupon code.

As we previously mentioned, the Costco coupon book lists “everyday low price” items as “your cost,” which is calculated by taking the featured March 2024 Coupon Book “instant savings” amount off the warehouse price to show the final sale price for the current month. After the current coupon book is expired, check back here as we upload the new ad preview as soon as it’s available, which is usually a few days before the offers go live.

More Costco Member Deals

Costco’s Executive and Gold Star Memberships

Don’t forget that if you’re a loyal Costco customer who spends at least $230 per month over the course of a year, it would benefit you to sign up for Costco’s Executive Membership — the year-end reward certificate (2% back on purchases) basically pays for your membership fee. If you’re a less frequent Costco shopper you can opt for the Gold Star Membership instead. It’s only $60 a year and you can use it at any Costco Wholesale club in the world. The Costco membership is also fully refundable if you’re not satisfied with it, so there’s not much to lose. Several times throughout the year we also see new membership deals from Costco where you can get a one-year Gold Star Membership plus a $20 Costco cash card and an online coupon for $25 off $250 or more at That’s a great deal!

The Costco App

Plus, Costco has introduced a digital card membership through the Costco app to make your life even easier, especially if you ever forget your shop card at home. It looks like it works on basically everything except gas stations, so now all you need to do is flash the app when you walk into a Costco store and you’re good to go.

Meal Deals at the Costco Food Court

And let’s not forget the steal that is the Costco food court. You can get a big meal for only a few bucks. The Costco hot dog and soda combo for $1.50 (the price is unchanged since 1985) is hard to beat, and the pizza is a perfect snack as you exit the store after having spent way too much money and time in there. For other Costco coupons, promo codes, deals and offers, check out the Costco coupons page on Slickdeals, or visit the Warehouse Savings section on Costco’s website for all active member-only savings (Note: the next round of savings should drop again soon, so make sure to set a Deal Alert.
