Grab your freezer bags, because Costco’s newest coupon book just made one of the warehouse’s most-loved treats even sweeter. Starting July 27, members can score a 24-count box of Oreo Mini Frozen Dessert Sandwiches for $6.59 — a full 31% off the regular price — and honestly, we’re already planning our next warehouse run around it.
The Deal: 31% Off a Costco Freezer Favorite
The new August Costco Coupon Book runs July 27 through August 23, 2026, and the Oreo Mini Frozen Dessert Sandwiches are one of the standout grocery deals inside it. Regularly priced between $9.59 and $10.79 depending on your warehouse, the box drops to $6.59 for the promo window — savings you get automatically at checkout, whether you’re shopping in-store or online, no clipping required.
Each box comes with 24 individually wrapped mini sandwiches, packaged in eight 3-packs, so they’re ready to toss straight into lunch boxes, coolers, or your own freezer stash without a mess.
“Seriously our new favorite ice cream sandwich. Please never discontinue this!”— Costco shopper
What Makes These Mini Sandwiches So Good
These aren’t just shrunk-down versions of a classic ice cream sandwich — Oreo built them from real Oreo cookie pieces, layered around a creme-flavored frozen dairy dessert. Distributed by Dreyer’s Grand Ice Cream under license from Mondelez, they land right in that sweet spot between “genuine Oreo flavor” and “portion control you can actually stick to.” Each mini sandwich clocks in around 60 calories, and a full serving of four comes to 190 calories — which makes it a whole lot easier to say yes to seconds (or thirds) without the guilt spiral.
If you’ve already stocked up on Costco’s Waffle Cone Bar Cake, these mini sandwiches are the perfect grab-and-go partner for it — one’s built for parties, the other’s built for whenever the freezer calls your name at 9 p.m.
Where (and How) to Score the Deal
The Oreo Mini Sandwiches have been popping up steadily in Costco freezer cases all summer, with shoppers spotting them in warehouses from coast to coast, and content creators like The Grocery Lady and Linda Savings featuring them in their “new at Costco” hauls this month. Pricing does shift slightly by location even outside the sale — some stores have already been ringing them up closer to $9.59, others closer to $10.79 — so the coupon book discount is a genuinely good moment to grab a box no matter where you shop. The deal is valid both online at Costco.com and in-store through August 23, and it applies automatically for anyone with a membership, so there’s no coupon to dig out of your bag.
One tip if you’re stocking the freezer for a party: buy an extra box. This size disappears fast once kids (or, let’s be honest, adults) discover they can eat “just one more” without much guilt. And because each sandwich is individually wrapped, they hold up well for road trips, lunchboxes, or tossing straight into a cooler for a pool day — no need to portion anything out yourself.
Pair it with something cold from the other end of the freezer aisle, like Costco’s $22.99 Strawberry Streusel Cheesecake, and you’ve basically got a dessert table ready for your next backyard hangout.
Should You Add This to Your Cart?
At $6.59 for two dozen individually wrapped sandwiches, this is one of those Costco buys that’s genuinely hard to argue with — it stores easily, travels well, and keeps for weeks in the freezer without losing that classic Oreo crunch. Add it to your list before the coupon book expires on August 23, and don’t be surprised if it disappears from your freezer faster than you can restock it.
