18 Costco Grocery Items Maryland Shoppers Buy to Save Big

Costco isn’t just for bulk toilet paper and TVs. For Marylanders looking to save on everyday groceries, it can be one of the smartest places to shop.

Some prices beat the grocery store by a mile, especially on things you buy all the time—like eggs, cheese, and frozen fruit. If you’ve ever filled a cart at a regular store and felt shocked at the total, Costco might help stretch your budget.

Let’s take a look at the groceries that almost always cost less at Costco.

Eggs Are Often a Fraction of Grocery Store Prices

Costco sells eggs by the dozen or even by the two dozen, and the price per egg is usually much lower than at the average supermarket.

Whether you’re baking, meal prepping, or just love breakfast, buying in bulk can save a lot of money over time.

You get more, pay less, and don’t have to run back to the store every few days.

It’s one of the most consistent grocery bargains you’ll find in the whole warehouse.

Cheese Blocks and Shredded Cheese Come at a Deep Discount

Cheese can be pricey at regular stores, especially if you’re buying name brands or larger packs. At Costco, you get more for less.

The shredded bags are huge, and the blocks last a long time in the fridge. Some people even freeze extra for later.

You don’t have to sacrifice quality, either. The prices are lower, but the taste holds up.

For families or anyone who cooks often, this one’s a no-brainer.

Rotisserie Chickens Are Famous for Their Value

Costco’s rotisserie chickens are one of the best-known grocery deals out there. They’re big, seasoned well, and stay at the same low price no matter what.

You could buy the same size chicken raw at another store and still pay more just to cook it yourself.

Use it for dinner, shred the leftovers for sandwiches, or make soup the next day.

It’s hard to beat a hot, ready-to-eat meal at this price.

Frozen Fruit Is Cheaper and Comes in Bigger Bags

Smoothie lovers know frozen fruit can add up fast at the grocery store. At Costco, the bags are huge, and the cost per ounce is way lower.

You’ll find blends with strawberries, mango, pineapple, and more. Some are even organic.

These big bags last a while in the freezer and make breakfast or snacks a lot more affordable.

It’s a smart pick for anyone trying to eat healthier on a budget.

Maple Syrup Costs Less by the Ounce

Real maple syrup is expensive at most stores, and the bottles are usually small. At Costco, you get a large jug of 100% pure maple syrup for much less per ounce.

It tastes great, lasts a long time, and doesn’t have all the fillers or added sugars found in cheaper brands.

You only need a little, but having it on hand makes every pancake morning better.

And you won’t be racing through tiny bottles week after week.

Coffee Beans and Grounds Are a Smart Bulk Buy

If you drink coffee every day, Costco can save you a lot over time. The bags of beans or ground coffee are larger, but the price per cup is much lower than at the grocery store.

They carry well-known brands and their own house label, which many people actually prefer.

You can even find organic and specialty roasts at a better price than you’d see elsewhere.

It’s one of the easiest upgrades for your morning routine.

Peanut Butter Comes in Bigger Jars for Less

Peanut butter is a staple in many homes, and at Costco, it’s sold in large twin packs that cost less than two small jars from other stores.

Whether you go for creamy or crunchy, the savings add up.

The quality is just as good, and some options include natural or organic versions too.

It’s perfect for school lunches, baking, or a quick spoonful straight from the jar.

Honey and Jam Are Cheaper in Family-Size Containers

Costco sells honey and jam in large bottles and jars that go a long way without costing a fortune. These pantry staples are ideal for toast, tea, and baking.

You’ll often pay double for the same amount at a regular grocery store.

The quality is still there, and the variety includes both brand names and Kirkland Signature items.

Buying them in bulk means fewer trips to restock.

Cooking Oil Comes in Larger Bottles for Less

Whether it’s olive oil, avocado oil, or vegetable oil, Costco sells it in bulk at a lower price per ounce than most grocery stores.

You might be buying a gallon instead of a small bottle, but it lasts a long time if you cook regularly.

The quality of the oil is usually high, and many options are organic or cold-pressed.

For home cooks, this is a dependable pantry item that’s worth buying in bulk.

Canned Tomatoes and Beans Offer Huge Savings

If you use canned tomatoes or beans for soups, chili, or pasta sauce, Costco gives you multi-packs for far less than buying them one at a time.

You’ll usually get six or eight cans in a shrink-wrapped bundle, and they don’t go bad anytime soon.

Stocking up this way saves time and money, especially for batch cooking.

Plus, you’re always ready to make a meal from scratch.

Butter Is Sold in Bulk Packs at a Lower Price

Butter can get expensive, especially during baking season. Costco sells it in four-stick or even eight-stick packs at a better price than most stores.

You can freeze extra sticks until you need them, so nothing goes to waste.

Both salted and unsalted varieties are available, and the price usually beats what you’ll find at smaller chains.

It’s a smart buy for anyone who cooks or bakes at home.

Bagged Salad Mixes Are Fresher and Cheaper

Costco’s salad kits are popular for good reason. They’re big enough to feed a family and often include toppings, dressings, and fresh greens at a lower price per ounce.

They’re ready to eat and often last longer than store-brand bags from smaller grocers.

Whether you want a Caesar kit or something with kale and cranberries, the value is clear.

It’s an easy way to eat healthy without spending a fortune.

Yogurt Packs Are a Great Deal for Families

At Costco, you can grab large tubs of plain yogurt or multi-packs of individual cups for less than what you’d pay at a traditional grocery store.

Flavored yogurts, Greek varieties, and even organic options are available.

They’re perfect for breakfast, lunchboxes, or quick snacks.

The price per serving drops way down when you buy them in bulk.

Baking Essentials Cost Less and Last Longer

Flour, sugar, baking soda, and chocolate chips are all cheaper at Costco, and you get way more for your money.

If you bake even once a month, stocking up on these basics can make a big difference.

The larger bags stay fresh for months if stored properly.

And it’s nice knowing you won’t run out halfway through a recipe.

Granola and Trail Mix Are More Affordable in Bulk

Granola and trail mix can be surprisingly expensive in small bags. At Costco, you get double or triple the amount for a better price.

The quality is high, with plenty of mixes including nuts, seeds, and dried fruit.

Great for snacking, topping yogurt, or packing for work and school.

It’s a smart grab for anyone who likes convenient, healthy snacks.

Milk Prices Are Lower Per Gallon

Milk is something many families buy weekly, and Costco often sells it for less per gallon than chain grocery stores.

You won’t find fancy packaging or a huge variety, but the basics are there—and cheaper.

It’s one of those simple staples that quietly saves money over time.

Buying it during a regular Costco run makes sense if you’re already there.

Cereal Boxes Are Bigger and Cost Less

Costco sells cereal in jumbo twin-packs or oversized boxes that bring the cost per ounce way down compared to grocery store prices.

You’ll find popular brands along with store-brand versions that taste just as good.

If your household goes through cereal quickly, this is an easy way to save.

And you won’t need to restock every week.

Snack Packs for Kids Are a Better Deal by the Count

From applesauce pouches to fruit snacks and granola bars, Costco’s bulk snack packs are priced lower per item than those sold at regular stores.

The big boxes last longer, which means fewer trips to the store.
