Perfect for lunches at day camp or to keep in a cooler at the beach to satisfy thirst, Kirkland Signature Organic 100% Juice boxes are a bulk essential for summer. The 40-count package retails for $15.49 and can even double as mixers for adult beverages at parties, barbecues, or bonfires.

Yes, you’re probably buying these all year if you have kids. But summer is the best time to shop at Costco in general, and cold juice hits the spot on warm, lazy days.

Toss a refrigerated Kirkland Signature Organic Applesauce pouch into your kid’s lunch bag or your beach tote and you have a treat that requires no utensils to eat and doubles as a cold pack. This comes in a 24-count package and costs $10.99.

Many kids who don’t like fruit still like applesauce. Because it’s in a sealed pouch, it’s convenient to take on the go. Be cautious about freezing these, as they may burst as they thaw.

They offer healthy protein for adults, too, especially for hikes or water sports. And they’re so easy to pack and bring along.

You’re outside all day and don’t have the time or desire to clean and chop produce. So, open a bag of the Eat Smart Chopped Salad Kit and pair it with a dressing your family loves. The two-count package retails for $5.99 and is the perfect fresh vegetable side to go with the dinner you’re grilling.

Or mix a bagged salad with cooked pasta and cubed chicken and dressing for an easy one-bowl meal for a picnic or potluck. These bagged salads are creative and hearty and one of the best benefits of a Costco membership.

Kirkland Signature Grass-Fed Beef Patties

Summer is for grilling, and Kirkland Signature Grass-Fed Beef Patties are delicious and easy to prepare because they’re already portioned and shaped. Buying frozen in bulk from Costco — a 15-count package retails for $29.49 — gets you a great deal on grass-fed beef.

These beef patties are a great example of the truth that smart ways to save money at Costco are really simple. The best way to save is by buying things you were going to purchase anyway, just in better quality and at a better price.

Kirkland Signature Chicken Breasts


Chicken breasts are the most versatile protein around, and they’re perfect for hot summer days when you don’t want to turn on the oven. Just toss Kirkland Signature Chicken Breasts on the grill outside, or in the Instant Pot or air fryer to keep your kitchen cool.

These boneless and skinless chicken breasts come in a 6.5-pound package for $22.99. Marinate them in bottled dressing, barbecue sauce, Greek yogurt, or any dry rub of your favorite spices. Serve with salad from a bag and frozen fruit sorbet for dessert, or pack them to serve cold at the beach or on a hike the next day.

Sweet Baby Ray's Barbecue Sauce

Sweet Baby Ray’s Barbecue Sauce goes on everything. This two-count package retails for $6.99. Marinate chicken, pork, fish, tofu, tempeh, or mushrooms in it for grilling. Toss some in the slow cooker or Instant Pot with chicken or beans. Mix with mayonnaise or sour cream or yogurt for a dressing for salads or mix with vegetables or use it to top burgers.

You can even mix this barbecue sauce with a vinaigrette dressing for a dressing at picnic salads that’s less greasy than mayo- or dairy-based dressings. The sweet, tangy taste just screams summer, and it elevates anything you’re ready to serve your family.

Kirkland Signature Organic Blueberries
