Did you know you can buy a vending machine at Costco? Members will tell you they might not have known, but it's not really a surprise. Most people with a Costco card expect off-the-wall finds at the warehouse and everything you need to make those finds fit perfectly into your life. They also know that Costco carries a gigantic selection of snacks to stock that vending machine. It could easily be filled with Costco's popular staples, like Kirkland Signature Nut Bars, Caramel S'mores Clusters, a variety pack of Frito Lay's chip bags, and plenty of Kirkland beef sticks. Members love to comb the aisles for fresh treats to add to the kitchen, and quite a few trendy snacks have landed on the shelves since January.

Functional snacks are everywhere at Costco in 2026, just like at all the other major grocery stores. Soda is infused with probiotics (whatever they really are), collagen is hidden in popcorn, and sugar levels are getting lower in a lot of snacks these days. Costco has been doing the same thing by introducing pared-down, nutrient-dense snacks that are additive-free but still deliver strong flavors. We've made a list of the 10 best new snacks on Costco shelves so far this year. Consider stocking up on some of these during your next visit, especially if you like to get your back-to-school snacks at Costco. Be sure to head to Costco on a weekend afternoon if you want to grab the most free samples while you're there. And remember, prices and store inventory can be different between Costco locations.

Costco's new Kirkland Signature Sea Salt Popcorn is made with just three ingredients: popcorn, coconut oil, and salt. It comes pre-popped in a box of 36 individual bags for $11.99. The bags are only 100 calories each, and some people say it's better than name brand popcorns. "Skinny pop better watch out, [sic]" wrote one shopper. Customers think it's close to what you'd get at the movies, with the added bonus of being dairy-free and lower-calorie while still having a buttery taste. "Can confirm doesn't taste like coconut and I can compare it to movie style popcorn," noted one person on Reddit. "Very good and clean."

Joolies Watermelon Date Sours are whole organic dates that have been pitted and dusted in a sour candy-style coating. They've become an obsession for fans of natural ingredients and sour gummy-style candy since they bring the two worlds together in a treat that actually works. Joolies makes these sour dates in a variety of flavors, including blue raspberry and peach. The watermelon flavor that arrived at select Costco stores in August is in a bigger bag – you get 16 ounces for $14.89 at the membership warehouse as opposed to the 4.5-ounce bags available elsewhere.

Wild Fox Foods Cocoa Crunch Protein Mix is a snack made with almonds, cashews, pumpkin seeds, raisins, and protein cocoa drops (aka chocolate chips). It was launched in select Costco locations in May and comes in a 26-ounce bag. The trail mix-style snack has 7 grams of protein per serving, is made with avocado oil and is free of gluten, seed oils, refined sugars, and additives. "This is a very good and pretty healthy snack," wrote one reviewer at Target. "The chocolate and raisins give it the perfect amount of sweetness and there are a lot of cashews, which is rare for mixed nut snacks."

Rotten Sour Gummy Cruncheez are a true gummy candy that came out in Costco warehouses in April. Each package on Costco shelves contains eight 1.8-ounce bags of candies and is selling for $14.99. Similar to Nerds Clusters, these have a gummy center with a crunchy shell of candy pieces around the outside, but these have become popular for being a low-sugar alternative. "Crunchy, gummy, and totally weird in the best way," said one Facebook reviewer. Others who have tried Rotten Sour Gummy Cruncheez say they're not quite sour enough to make you pucker, but they are tart.

Nightingale Brookie Dough Ice Cream Sandwiches are about half the size of a regular ice cream sandwich, so they're bite-sized (or chomp size, as the brand calls it). They're more than just a basic ice cream sandwich, though. These frozen treats consist of cookie dough ice cream stuffed between a brownie cookie and a chocolate chip cookie. A 12-pack of Nightingale Brookie Dough Ice Cream Sandwiches costs $14.99, and when they showed up at select Costco locations in May they were hailed as the perfect, snack-sized summer treat. Social media commenters have noted that the mini sandwiches are built well and have the structure needed to be a true ice cream sandwich, and that they're a great option if you want something sweet but not a full-sized dessert.

Tuscanini Snacking Olives deliver the flavors of Italy without the hassle of booking a plane ticket. They arrived at Costco in January in a bag that contains 12 individual packs of buttery, briny Sicilian olives for $9.89. Customers say the individual packages are convenient and the olives have a pleasant texture. Plus there's no spillable liquid inside, so they're a great option for school lunches and on-the-go snacking. These olive snacks are made with just two ingredients, olives and salt, with the added bonus of being a heart-healthy snack.

GoodPop Fruit Sours combine sour candy and fruity popsicles into one frozen treat, and Costco customers are thrilled. They arrived in a 16-count box selling for $12.59 at select Costco locations in late spring 2026 and immediately drew attention for being super flavorful. Each box contains melon, green apple, and lemonade-flavored popsicles made with a real fruit-based center and a sour candy powder outer coating. People are definitely puckering when they eat these but stay it's a nice balance of fruity and tart.

Calbee Shrimp Chips Variety Pack brought another Japanese-style snacking experience to Costco in January. The $12.99 box contains 24 bags of shrimp chips in three different flavors: Original, Hot Garlic, and Sriracha Mayo. Members are using them to add some variety to their back-to-school snacks, on road trips, or simply to satisfy a craving for something crunchy. They point out the little packs of shrimp chips are convenient and carry a ton of flavor.

Costco added a mini charcuterie board to its inventory in the summer of 2026 with the introduction of Upper Cut Curated Tapas Snack Packs. For $12.59, you get three snack packs that contain four different snackable ingredients. Each pack has a section of white cheddar, uncured salami, dark chocolate-covered cranberries, and rosemary and olive-oil crackers. Members love that the components are high quality without all the junk you get from most pre-made meat and cheese platters. It's a little taste of Spanish tapas without you having to track them down at a restaurant.
