Okay, grab your cart and hold onto your gut biome, because Costco just brought back the soda everyone loses their minds over every single year: Poppi Cranberry Fizz is BACK on shelves, and shoppers are already treating the warehouse aisles like a Black Friday doorbuster. If you’ve never seen adults sprint toward a soda display, this is your sign to witness it in person.
We’ve watched Poppi go from “that gut-health soda my TikTok algorithm won’t stop showing me” to an honest-to-goodness cult phenomenon, and Cranberry Fizz is the flavor that started the whole obsession. Costco is stocking it again for the cozy season, and based on how fast it’s flying off pallets, you’ll want to add it to your list before your next trip, not after.
What Exactly Is Poppi Cranberry Fizz?
Poppi built its whole brand on being the soda you can feel a little smug about drinking: it’s made with prebiotics, a splash of apple cider vinegar, real fruit juice, and way less sugar than a regular can of pop. Cranberry Fizz is the seasonal flavor fans wait for all year, delivering a light, blush-pink soda with crisp bubbles and a tart cranberry finish that hits on the back of your tongue rather than smacking you over the head with sweetness.
Each can comes in at around 25 to 35 calories and less than 5 grams of sugar, so it genuinely splits the difference between a diet soda and the real thing without tasting like either. Costco is currently selling the 15-pack of 12 fl oz cans for about $18.49, which works out to roughly $1.23 a can — a noticeably better deal than the $2-plus per can you’ll pay grabbing singles elsewhere.
“It’s a well-balanced beverage that I can feel good about drinking. The cranberry flavor hits you on the back end of your palate and adds a subtle twang to a standard white soda.”
Why Shoppers Are Losing It Over This Restock
This isn’t Poppi’s first rodeo at Costco, but Cranberry Fizz has a reputation for selling out fast every time it reappears, and this year is shaping up to be no different. Shoppers have been flooding comment sections with reactions ranging from “running to costcoooo” to “I audibly gasped” the moment word got out that pallets were hitting warehouses again. One shopper straight-up admitted they “may or may not have stocked up,” which, relatable.
Part of the appeal is timing: Cranberry Fizz shows up right as everyone starts craving cozier, fall-and-holiday flavors, but it still feels light enough to drink by the case instead of just sipping one and calling it a treat. It’s basically the gateway soda for people who want festive vibes without the sugar crash that comes with traditional holiday drinks.
Is It Worth Adding to Your Cart?
If you’ve tried other Poppi flavors and liked them, Cranberry Fizz is an easy yes — it’s consistently ranked as one of the brand’s most requested seasonal drops, and the Costco price genuinely undercuts what you’d pay buying it flavor-by-flavor at other retailers. If you’re new to prebiotic sodas, this is a solid one to start with since the cranberry flavor is subtle rather than overpowering, so it doesn’t taste like you’re drinking a health supplement pretending to be a soda.
The only real downside? Fans have been begging Poppi to make this one a year-round flavor instead of a limited seasonal drop, so once it’s gone, it’s gone until it (hopefully) resurfaces again. If your warehouse has it in stock, don’t just add it to the list for “next time” — treat it like the limited drop it actually is.

The move: check your Costco app or call ahead before making a special trip, grab the 15-pack while it’s there, and maybe toss an extra one in the cart for your neighbor who’s going to be so mad they missed it. Happy hunting, and let us know in the comments if your warehouse still has it in stock!
