If you’ve been wandering the beverage aisle at Costco lately, you may have spotted something that’s equal parts nostalgia and health trend: an 18-pack of Poppi Shirley Temple prebiotic soda for just $26.49. And yes, people are absolutely losing it over this find. Cute cherry packaging, a childhood flavor you forgot you missed, and actual gut benefits? That’s a summer trifecta we didn’t know we needed.

Wait — What Is Poppi, Exactly?

If you haven’t jumped on the prebiotic soda train yet, buckle up. Poppi is one of the hottest drinks in the wellness world right now. Each can packs apple cider vinegar, prebiotic fiber, and just 5 grams of sugar — all wrapped up in flavors that actually taste like real, satisfying soda. Not “healthy soda.” Just delicious, fizzy, crave-it-every-day soda.

The brand blew up on TikTok before landing a major Pepsi partnership, and it’s been showing up everywhere from Whole Foods to, now, your favorite warehouse store. The Shirley Temple flavor — inspired by the classic cherry-grenadine mocktail beloved since the 1930s — is one of Poppi’s most popular. It’s sweet, tart, and just a little fancy, with that unmistakable maraschino cherry vibe. And at Costco? You get 18 cans for $26.49. That works out to about $1.47 per can, compared to $2.29–$3.49+ at most grocery stores. Yes, really.

The Numbers That Actually Matter

Let’s talk value, because this deal is legitimately impressive for a brand that usually commands premium pricing:

  • 18-pack at Costco: $26.49 (~$1.47/can)
  • Typical retail price: $2.29–$3.49/can
  • Calories per can: ~30
  • Sugar per can: 5 grams
  • Caffeine: Zero
  • Prebiotic fiber: ✅ Yes

Basically, this is the guilt-free summer sip that won’t blow your budget or wreck your gut. Add a maraschino cherry and a sprig of mint, and you’ve got the fanciest drink at the cookout — no bartender required.

“All the nostalgia of a Shirley Temple, none of the sugar crash, and Costco pricing to seal the deal.”

How to Make a Dirty Shirley With Poppi

Here’s a pro tip for your next summer gathering: mix one can of Poppi Shirley Temple with an ounce of your favorite vodka and a squeeze of lime. The result is a Dirty Shirley cocktail that’s low-sugar, prebiotic-packed, and shockingly delicious. Your guests will ask for the recipe. You’ll smile and just hand them the Costco box.

Not into cocktails? No worries — Poppi Shirley Temple is equally perfect straight from the can over ice, or mixed half-and-half with lemonade for a cherry lemonade spritz that screams summer. Kids love it. Adults love it. Even people who claim they don’t drink soda anymore will secretly reach for a second can.

Costco Is Nailing the Viral Food Trend Game This Summer

Costco has been absolutely crushing it this summer when it comes to stocking fun, TikTok-trending finds at prices that make sense. We’ve already raved about their $11.49 fruit-shaped ice cream bars that have been breaking the internet, and those $9.99 pistachio croissants that had pastry fans doing a happy dance in the bakery aisle. Now Poppi Shirley Temple earns its spot on that elite list of “things I didn’t know I needed from Costco but now can’t live without.”

The prebiotic soda category has exploded in 2026, with brands like Poppi and Olipop racking up billions of social media views and landing major grocery chain placements nationwide. Getting a fan-favorite flavor in an 18-pack at Costco value pricing is exactly where the wellness trend meets real-world budgets — and that’s a lane GroceryGoodies loves to live in.

Should You Grab It? (Spoiler: Yes.)

Absolutely — and sooner rather than later. Costco rotates its specialty beverage finds, and there’s no guarantee the Poppi Shirley Temple 18-pack sticks around through August. If you’ve been curious about prebiotic sodas but hesitated at paying $3+ per can at regular grocery stores, this is your sign. Eighteen cans at ~$1.47 each is a risk-free way to find out what everyone’s been talking about.

Odds are, you’ll be reaching for a second box before July 4th rolls around. 🍒

Pro tip: Check the Costco app or your local warehouse’s stock before making the trip — availability can vary by location, and this one tends to move fast once word gets out.
