Kirkland Signature Trail Mix Snack Packs
Price: $19.99
Kirkland Signature trail mix snack packs are a go-to for summer bags, beach totes and road trips. Each individually wrapped pouch contains peanuts, M&M's, raisins, almonds and cashews, covering sweet and salty in one grab. At $0.71 per pack, this is a fraction of what you'd pay at a convenience store or airport kiosk.
Kirkland Signature Extra Fancy Mixed Nuts
Price: $18.49
The Kirkland Signature extra fancy mixed nuts are one of the best all-around snack values in the warehouse. The salted variety packs cashews, almonds, pecans, Brazil nuts and macadamia nuts into a 40-ounce resealable bag — which is only $0.46 per ounce. This is the kind of bulk buy that works equally well for a party spread, lunchbox snacking or poolside munching all summer long.
Olipop Soda Variety Pack
Price: $24.99
OLIPOP Soda variety pack brings together three fan-favorite flavors — Cream Soda, Classic Grape and Classic Root Beer — in a Costco-exclusive size of 15 cans. Olipop is made with plant fiber and botanicals that support digestive health, and it's a smart stand-in for traditional soda at summer parties. Single cans typically retail for $2.49 or more, so the Costco pack cuts that cost nearly in half.
Liquid I.V. Hydration Multiplier Variety Pack
Price: $32.99
Staying hydrated in summer heat isn't just about drinking more water. It's about making that water work harder. The Liquid I.V. Hydration variety pack uses cellular transport technology to deliver electrolytes and nutrients more efficiently than water alone, and Costco's 30-count variety pack keeps you stocked through the hottest weeks of the season. At roughly $1.10 per stick, it beats single-box pricing at drug stores and grocery chains by a wide margin.
SunChips Whole Grain Variety Pack
Price: $21.99
SunChips whole grain variety pack covers the party chip spread with 30 individual bags across four flavors: harvest cheddar, garden salsa, original and french onion. Made with 100% whole grain corn and 30% less fat than regular potato chips, these are a lighter option that don't sacrifice flavor. At $0.73 per bag, this is an easy choice for summer picnics, kids' lunches and cookout snacking.
Chomps Original Beef Sticks
Price: $21.99
Chomps original beef sticks are one of the cleanest protein snacks on the Costco floor — grass-fed, gluten-free and free from antibiotics. With 9 grams of protein per stick, they're a go-to for hikes, long days at the pool or keeping hunger at bay between meals. These typically sell for $2.50 or more per stick at specialty grocers, making the Costco pack a genuine find.
Kirkland Signature Organic Lemonade
Price: $7.59
Kirkland Signature organic lemonade delivers two 96-ounce bottles — that's nearly 24 cups of lemonade — for under $8. It's USDA organic and made from organic lemon juice concentrate and organic sugar, with no artificial colors or flavors. This is the kind of effortless summer crowd-pleaser that works as-is over ice or mixed into lemonade slushies and cocktails for backyard parties.
Gatorade Thirst Quencher Core Variety Pack
Price: $18.99
The Gatorade thirst quencher core variety pack gives you 28 bottles of lemon-lime, fruit punch and orange for just over $0.68 each. Whether you're stocking a cooler for a soccer tournament, rehydrating after yard work or keeping the kids fueled at the park, this 28-pack covers the full summer without a second trip to the store.
