7 Costco Grocery Items That Can Save You Hundreds of Dollars Annually
Most people realize you can save money shopping at Costco, especially if you have a big family and want to buy common household goods in bulk. But you can also save a ton on groceries year-round at the wholesale club.
Your best bets are items that will either be consumed quickly or can last a while without expiring. That giant container of cinnamon or garlic powder is probably not a good idea unless you’re cooking restaurant-level quantities of food weekly. But if your family of four eats two eggs each per day, you’ll go through two dozen pretty quickly.

Let’s look at some of the best grocery items that will help you save money at Costco.
Keep Shopping: The Best Costco Buys To Grab Now Before Summer Ends
Kirkland Signature Eggs
Price: $3.73
Grab two dozen eggs for less than $4 and pretend your grocery bill is from 2019. A high-protein staple in many households, you can save even more by purchasing Costco’s giant five-dozen package. But it’s nice to have the smaller option with Costco-sized savings.
Kirkland Signature Butter
Price: $11.34 (originally $13.34)
The average price for 16 ounces of butter in one-quarter pound sticks was $3.93 in May 2026. Prices may be higher in some areas. You’ll pay more for brands like Land O’ Lakes. You can get 4 pounds of Kirkland salted butter for just over $11, a savings of at least $1 per pound.
Kirkland Chunk Chicken Breast
Price: $16.99
At less than $3 per can (in a pack of six), with roughly 3.5 servings per can and 13 grams of protein in each serving, Kirkland's chunk chicken breast in water packs in a lot of protein per dollar. Use this handy pantry staple to whip up a quick batch of chicken salad or chicken soup or mix it in a casserole to stretch your grocery budget.
Kirkland Signature Organic Chicken Stock
Price: $11.99
Kirkland’s six-pack of organic chicken stock costs just $2 for 32 ounces and is shelf-stable for a full year. Chicken stock typically costs more than $2 for a 16-ounce carton at grocery stores. When you factor in the cost of chicken, seasonings and canning equipment, this stock costs even less than making your own.
Honey Nut Cheerios Cereal
Price: $9.86
Not all of the best Costco grocery deals are the club’s private-label Kirkland brand. You can find excellent savings on cereal like General Mills Honey Nut Cheerios. Costco offers two 27.5-ounce bags for $9.86, roughly 18 cents per ounce. Walmart lists a 10.8-ounce package at $3.47, almost double the price per ounce.
Rao’s Homemade Marinara Sauce
Price: $14.74
Rao’s is a market leader when it comes to premium pasta sauce brands, but it carries a high price tag. You may get lucky and find it on sale at your local grocery store for $6 for a 24-ounce jar. But you can always snag a good price (around $7 each) on two 32-ounce jars at Costco.
Costco's Rotisserie Chicken
Price: $4.99
It’s impossible to mention Costco’s best grocery deals without pointing out the famous rotisserie chicken. A loss leader for years, the $5 precooked, warmed chicken has been around $5 since 2009 and Costco has no intentions to raise the price, according to RealSimple.com.
The downside is that some states charge tax on the chicken since it’s sold hot and ready-to-eat, and it’s not eligible for SNAP benefits for the same reason. If you’re looking to use EBT to buy Costco’s rotisserie chicken, you can find cold, shredded chicken in packages near Costco’s other prepared, packaged foods that make for an easy dinner.
