Costco is famous for deep discounts and bulk buys. And while there is a revolving lineup of new and seasonal products that fans rave about, some of these bargain buys are staples that shoppers seek out every month.
A Gold Star membership costs $65 a year, and an Executive membership costs $130 and earns a 2% annual reward on qualifying purchases, so stocking up on the right staples can help your membership pay for itself.
If you're looking for the best Costco shopping hacks, we can help. From coffee pods to creme-covered almonds, these are the top picks to put on your shopping list every month. The retailer's everyday low prices make it easy to keep your monthly shopping budget in check.

Kirkland Organic Tomato Sauce
Price: $13.99
Homemade pizzas, spaghetti, and lasagna all need sauce. And there's no reason to pay brand-name prices. For $13.99, you can score a 12-count pack from Kirkland Signature.
The sauce is made from organic California Roma tomatoes that are vine-ripened and freshly packed, and it's USDA Organic and kosher.
A single 15-ounce can of Hunt's costs $1.49 at Target. At that price, you would pay over $17 for the same quantity as Costco's bulk buy.
That works out to about $1.17 a can at Costco. Because it's a simple base sauce, you can season it your way with garlic, herbs or red pepper flakes, or use it in chili, soups and stews.
Kirkland Organic Dried Blueberries
Price: $10.49
Add a healthy touch of sweetness to oatmeal, pancakes, or an ice cream sundae. Get over one pound of organic blueberries for less than $11 right now.
The 20-ounce resealable bag is kosher, and Costco suggests tossing the berries into salads or yogurt or mixing them into muffin, waffle or cake batter.
This mega-sized bag is the perfect take-along treat for on-the-go snacking. You won't have to worry about washing or refrigerating the dried fruit.
Keep in mind that these are sweetened: The ingredient list includes organic cane sugar and organic sunflower oil along with the organic blueberries. A quarter-cup serving has about 130 calories and 3 grams of fiber, so a small handful goes a long way.
Kirkland Solid White Albacore Tuna
Price: $18.99
Make tuna salad for the entire month with this protein-rich bulk buy. Each under-$19 box includes eight seven-ounce cans of wild-caught, water-packed solid white Albacore tuna.
Each can packs 42 grams of protein, and the ingredient list is short: albacore tuna, water, sea salt and sodium acid pyrophosphate. The tuna is dolphin-safe, kosher and traceable from sea to shelf.
Check your local Costco for an even better price. We found this eight-count pack for $15.79.
Solid white albacore has a firm, meaty texture that holds together well, so it works in sandwiches, salads, pasta and casseroles, not just tuna salad. At $18.99, each can costs about $2.37.
Kirkland Breakfast Blend Coffee Pods
Price: $44.99
Pass on the pricey brand-name K Cups and try Kirkland's generic coffee. You'll get 120 pods of the rich organic blend for less than $45. Keurig sells a smaller 96-count pack of Green Mountain Coffee's Breakfast Blend for over $50.
That works out to about 37 cents per pod for the Kirkland version. The Breakfast Blend is a light roast made from 100% Arabica beans, and it's Fair Trade Certified and kosher.
Costco describes its aroma as toasted walnut with malty brown sugar notes. The pods are made for Keurig K-Cup brewers, and once you're done, you can peel off the lid and compost the grounds. If you drink one cup a day, a single box lasts about four months.
Kirkland Sparkling Water
Price: $13.61
Kirkland's sparkling water is a bargain-priced dupe for LaCroix. The Costco brand 35-count pack includes lime, lemon, and grapefruit flavors.
Each 12-ounce can is calorie-free, sodium-free and sweetener-free, and the ingredient list is simply carbonated water and natural flavors. Drink the water over ice or mix it into a bubbling cocktail.
At $13.61, you'll pay about 39 cents a can. Reviewers say the fizz holds up, and one calls grapefruit the standout of the three flavors. Keep a few cans chilled for an easy soda swap.
Just don't confuse these cans with Kirkland's bottled sparkling water, which comes in different flavors and is sweetened with sucralose.
Kirkland Paper Towels
Price: $23.99
Messes happen, but you don't need to spend money on brand-name paper towels just to keep your home clean. This bulk-sized pack includes 12 individually wrapped rolls of two-ply 160-sheet paper towels for $23.99.
These are Create-a-Size towels, so you can tear off a half or full sheet depending on the mess. Each 11-by-7-inch sheet has two thick, absorbent layers, and the pack adds up to 1,920 sheets, or 1,026 square feet.
A 12-count pack of 135-sheet-per-roll Bounty costs $35.49 at Target. That means you'd get 300 fewer sheets with the Bounty pack while paying more. Since each roll is wrapped, you can stash a few in the garage or laundry room without worrying about dust.
Artisan Rolls
Price: $8.18
Warm bakery-fresh rolls from Costco? We aren't the only ones who enjoy this 12-count pack of artisan buns.
These ciabatta-style rolls are baked in the Costco bakery and come pre-sliced, with a slightly chewy crust and an airy, hole-filled interior. The ingredient list is short, with enriched wheat flour, water, sea salt, yeast and malted barley flour, and no preservatives.
Reddit user northwest333 raved, "These beautiful carbohydrate packets are so delicious and versatile. Use 'em for toast in the morning, a sandwich for lunch, and a side roll for dinner. There's probably something you can do for dessert too."
Because there are no preservatives, freeze any rolls you won't eat within a few days.
Multigrain Loaf
Price: $8.70
Oats, flax seeds, molasses, sunflower seeds, wheat berries, and brown sugar give this bakery bread a flavor you will savor.
The Kirkland Signature loaf weighs 32 ounces and also includes whole wheat flour, rye flour, millet, brown rice and a sour culture. Slice the bread and make a hearty gourmet grilled cheese, use it for French toast, or slather your favorite nut butter on top.
Each serving has about 130 calories. Keep in mind that enriched flour is the first ingredient, so it isn't a 100% whole-grain bread, and it isn't gluten-free. If you can't finish the loaf within a few days, slice and freeze the rest so you can toast pieces as needed.
Kirkland Organic Tortilla Chips
Price: $7.93
Prep for your next party with this super-sized bag of tortilla chips. For $7.93, you can get 40 ounces of the USDA organic white and yellow corn snack. A much smaller 17-ounce-size Tostitos Original Restaurant Style Tortilla Chips costs $6.69 at Target.
That works out to about 20 cents an ounce at Costco, compared with about 39 cents an ounce for the Tostitos. The chips are made with organic whole corn, organic sunflower oil and sea salt, and they're certified gluten-free, kosher and non-GMO.
Pair them with salsa, guacamole or queso, or crush the broken bits at the bottom of the bag over taco salads or chili.

Kirkland AAA Batteries
Price: $16.99
Batteries are essential. Whether you need them to power your TV's remote control or keep your smoke detectors in working order, these AAAs can power more than a few items in your house. This under-$17 pack includes 48 batteries with a 12-year shelf life.
That's about 35 cents per battery. These 1.5-volt alkaline batteries have no added mercury, and they work in everyday gadgets like wireless keyboards, computer mice, flashlights, toys and clocks.
The long shelf life means you can keep a stash in a drawer for when a remote dies unexpectedly. For best results, replace all the batteries in a device at once, don't mix old and new ones and never try to recharge them.
Kirkland Daily Makeup Remover Towelettes
Price: $15.99
Wipe away makeup, dirt, and more with these glycerin-infused hydrating towelettes. Each $15.99 box includes four 36-count reclosable flip-top packs and four 15-count resealable travel packs.
That's 204 towelettes in all, or about 8 cents apiece. The newer plant-based formula is dermatologist and ophthalmologist tested, and you can use it morning and evening to cleanse your face, with no rinsing needed.
Keep the flip-top packs on your bathroom counter and toss the travel packs in your gym bag, carry-on or car. Close the lid or label tightly after each use so the wipes don't dry out, and don't flush them.
Fans praise how large and moist they are, though a few say recent batches leave skin feeling oily.
Kirkland Chicken Breasts
Price: $3.39 per pound
Stock up and save on chicken at Costco this month — and every month. Instead of buying smaller quantities at a specialty grocery store, snag one of these multi-packs of air-chilled, vacuum-packed poultry.
The boneless, skinless breasts are hatched, raised and harvested in the U.S., with two or three breasts in each leak-resistant pouch. Package sizes vary by warehouse, with some averaging around 6 pounds and others closer to 8 or 9.
And don't worry about using it all right away. Tear-off pouches make it easy to freeze and store this bargain buy. Keep pouches in the fridge for meals this week and move the rest to the freezer.
Kirkland Bottled Water
Price: $4.53
While a reusable bottle is the best way to save money on water costs, this 40-count can also help you cut costs. Compare Costco's price to over $7 for a 32-pack of Poland Spring water.
At $4.53, each 16.9-ounce Kirkland Signature bottle costs about 11 cents, compared with more than 21 cents a bottle for the Poland Spring pack. The water is purified using filtration and reverse osmosis, and a proprietary mineral blend is added for taste.
It has zero calories and no sweeteners or artificial colors or flavors. The bottles are a handy size for school lunches, sports and parties, and the bottle, cap and label are 100% recyclable.
Kirkland Extra Fancy Salted Mixed Nuts
Price: $18.49
Plan for unexpected guests and stock up on these extra fancy mixed nuts. The blend of cashews, almonds, pecans, Brazil nuts, and macadamias is a fan favorite.
The nuts are roasted for a crunchy bite and seasoned with sea salt, and they come in a resealable pouch that helps keep them fresh.
This is a bargain at $18.49 for 2.5 pounds. Planters Deluxe Mixed Nuts sells for $12.19 at Target. But you'll get less than one pound. Costco's price works out to about 46 cents an ounce.
Set out a bowl for guests, sprinkle a handful over a salad or pack a few in a snack bag. Note that the ingredient list includes peanut oil, which matters if anyone in your home has a peanut allergy.
Kirkland Italian Extra Virgin Olive Oil
Price: $20.99
Olive oil can be added to almost everything, from pasta sauce and pizza to dips and even desserts. If you use olive oil in bulk, this is a Costco buy you can't pass up. You'll get two liters of the 100 percent Italian cold-extracted extra virgin olive oil for a bargain price.
The oil is produced from Italian-grown olives, and Costco says it has a traceable chain of Italian origin, meaning the olives are grown, pressed and bottled in Italy. The 67.6-fluid-ounce bottle is kosher and has thousands of reviews on Costco.com with a 4.8-star average.
Store it in a cool, dark spot away from the stove, since heat and light can dull the flavor over time.
Bottom line
You don't have to wait for sales, specials, or store coupons to save big at Costco. The bulk buy warehouse club has everyday low prices on pantry picks, bakery buys, sweets, treats, and more. And if you're not happy with a Kirkland Signature product, Costco will refund your money.
Stack your savings with the top cash back credit cards. You could score cash back, travel points, and other perks on your regular monthly haul.
If you shop at Costco often, an Executive membership adds a 2% annual reward on qualifying purchases, and Costco will refund the difference if that reward doesn't cover the $65 upgrade cost.
