There’s no doubt that Costco is the undisputed mother of bulk-buying heaven. As a seasoned Costco member and parent, I’ve navigated the vast aisles of this wholesale giant to find the most valuable deals and must-have items. So when folks are wondering about the best things to buy at Costco, you better believe I’m happy—THRILLED, even—to deliver in bulk.
Costco has revolutionized how families shop, offering unbeatable prices on bulk purchases. While I still enjoy specialty stores for certain items (miss you, Trader Joe’s), Costco has become my go-to for household essentials, pantry staples, and family-sized portions of our favorite foods. And my favorite surprise: Costco is the absolute best place to shop if you’re in the market for snacks and staples that are high in quality protein.

Best Pantry Finds at Costco
Seven Sundays Real Cocoa Grain Free Cereal, $11.22 for 16 oz
Made with wholesome ingredients like sunflower seeds, coconut, and real cocoa, this cereal is grain-free, gluten-free, and naturally sweetened. Each serving is high in protein and fiber, providing long-lasting energy and satisfaction. It’s perfect if you’re following a paleo or keto diet, or for anyone looking to enjoy a tasty, healthy breakfast. Bonus: my kids love it (and the “chocolate milk” it leaves behind).
Organic Creamy Peanut Butter, $12.86 for 28-oz, 2-count
IYKYK. No peanut butter tastes better than this. It’s perfect for this peanut butter snack cake or adding to smoothies. Or scooping straight out of the jar.
Organic Chicken Stock, $11.69 for 32 fl oz, 6-count
Chicken stock is a pantry staple when it comes to sauces, pastas, soups, or even livening up rice. Kirkland’s Organic Chicken Stock is delicious on its own, so you know it’ll pump flavor into whatever you’re cooking. Plus, it’s made from simple ingredients—the same simple vegetables and spices I’d use if I were making stock at home.
Siete Almond Flour Tortillas, $14.79 for 20-count
If you’re lucky enough to be in LA, Austin, or Hawaii, you’ll find these stocked at your local Costco. They’re a personal favorite of mine. They’re great for quesadilla night or a simple lunchtime wrap. We’re obsessed with everything the famed Austin-based brand puts out. And while these tortillas taste purely authentic, they’re also friendly on your digestive system and keep you from feeling weighed down post-meal.
Dave’s Killer Bread Sprouted Whole Grains, $11.10 for 2 loaves, 48 oz
This bread is packed with organic whole grains and seeds, making it a nutritious and filling option for sandwiches and toast. It’s a perfect choice for those looking to add more fiber and protein to their diet.
Kodiak Pancake and Waffle Mix, $15.08 for 72 oz
A solid protein-fueled breakfast is essential for kids (and your) brain health going into a day of school or work. When eggs or yogurt just won’t do, this mix gets the job done. And you can make more than just waffles or pancakes—the muffins and breakfast cookies are perfect to whip up for on-the-go AM meals or quick snacks.
Kirkland Signature Bagels, $7.99 for 12-count
If you’re someone who loves venturing out for your weekend bagel and coffee, I totally feel you. It’s a little luxury that I could always do with more in my life. But if you’re looking for a quick-and-easy option—whose price you can’t beat—Costco reigns supreme. I love that the bagels are water-boiled, making each nice and chewy on the inside while the exterior gets a crispy, golden-brown texture. I’d even go as far to say that their plain bagel is a treat—but the parmesan is my true fave.
Healthy Snacks at Costco
Simple Mills Almond Flour Crackers, $11.69 for 10 oz, 2-count2-Ply, 380 Sheets, 30 Rolls
You must always leave Costco with something crunchy and snacky in your cart. Simple Mills Almond Flour crackers are truly addicting and buying them in bulk is the most affordable way to go. These crackers pair well with cottage cheese for a healthy snack.
Trubar Protein Bars, $24.87 for 14-count
These protein bars are DECADENT and such a treat. Trubar is a woman-founded company and they knew what they were doing when they formulated protein bars that taste like cookie dough and donuts. Favorite Costco find of the year.
Humm Organic Probiotic Kombucha, $33.45 for 14-oz 12-count
Your favorite brands of kombucha in bulk? Yes, please! You can find Bend, Oregon-based Humm Organic Probiotic Kombucha on your local Costco shelves. Personally, even the Kirkland brand’s raw Ginger-Lemonade kombucha is a gut-friendly fave. Pro tip: Use it to make kombucha cocktails and thank me later.
Harmless Harvest Organic Coconut Water, $16.36 for 14-oz, 6-count
Named best overall in our coconut water taste test, Harmless Harvest is truly refreshing—and Costco sells them six in a box. Essential for summer hydration and so good in smoothies.

Meat & Fish from Costco

Wild Planet Albacore Wild Tuna, $19.88 for 5 oz, 6-count
This tuna is sustainably caught and packed with protein, making it a nutritious and convenient option for meals and snacks—like this tuna avocado toast. The albacore tuna is pole and line caught, ensuring minimal environmental impact and maximum quality. Plus, it’s rich in omega-3 fatty acids, essential for heart and brain health.
Best Refrigerated & Frozen Grocery Items to Buy in Bulk
Au Pain Doré Frozen Butter Croissants, $17.99 for 30-count
For a fancier take on a morning pastry, stock up on some delicious, buttery croissants. They’re excellent from the bakery, but the Camille Styles team has even raved about our mutual love of the brand’s frozen croissants. While Costco’s in-house Kirkland brand offers them, my favorite are those from Au Pain Doré (a Montreal-based bakery). Hot tip: Bake yours in the air fryer and brush on a little egg wash before popping them in. You’ll get the perfect golden-brown croissant.
Painterland Sisters Organic Skyr Yogurt, $17.54 for 8-count
This Icelandic-style yogurt is thick, creamy, and packed with protein. It’s a great choice for breakfast or a snack and can be topped with fruits, nuts, or granola.

Tillamook Medium Cheddar Slices, $12.27 for 52 slices, 2.5 lbs
These cheddar slices are rich and creamy, perfect for sandwiches, burgers, or snacking. My kids call it “flat cheese,” and they aren’t wrong. Whenever I want to give them an added protein boost, I pass them a slice.
Organic Valley Stringles, $11.45 for 24-count
These organic string cheese sticks are a fun and healthy snack for kids and adults alike. They are made with high-quality organic milk and are a good source of calcium and protein.

Top Costco Deals on Household Essentials
Pendleton Blankets, $26.99
No matter what your vibe is at home, Pendleton blankets are the perfect way to cozy up your space. If you’re familiar with Pendleton, then you’ll be as blown away as I was to find it on sale at Costco. Perfect for you or as a gift.
Kirkland Toilet Paper, $23.39 for 30 Rolls
It’s not furniture, but it’s a household staple nonetheless. Arguably one of my favorite items to get at Costco is toilet paper in bulk. It usually lasts several months and yes, is unbelievably soft. If you were also traumatized by TP Gate 2020, you’ll never miss an opportunity to stock up at Costco.
Kirkland Signature Paper Towels, $23.39 for 12-count
… same goes for paper towels. When it comes to Costco, the brand excels in both the little things that make life a luxury (see Pendleton blanket and croissants above) as well as the staples every day requires.
Favorite Costco Beauty & Supplements
Vital Proteins Collagen Peptides, $37.43 for 32.56 oz
Maintaining a protein-heavy diet can be expensive. However, at Costco, you’ll find tons of affordable options for protein powder and pre-mixed shakes. Vital Proteins are one of my favorite clean protein options, and you can find almost any variety of the popular brand’s protein blends (from marine collagen to collagen peptides and its standard protein powders).
Kirkland Signature Vitamin C, $19.99 for 1000mg., 500 tablets
We all know well that once you enter the supplements game, things can start getting expensive, fast.

I take this Vitamin C every day to keep my cells healthy and happy, and my body loves the results.
La Mer Skincare, Price Varies
Lastly, one of the most surprising brands I have found at Costco is La Mer. Think what you will of Kim K, but her skin is flawless—and La Mer skin cream is her fave. So, of course, I’m going to jump at the opportunity to buy it in bulk.
