Costco is known as a low-price leader, but as the big-box and warehouse store landscape becomes more and more competitive, it's getting harder to find unbeatable deals. Despite this, Costco still has some major purchasing power, which helps it keep costs way low.
That dynamic was a key ingredient in Costco's emergence as one of the biggest winners of the pandemic.
Organic Maple Syrup
Costco price: 37 cents an ounce
Walmart price: 85 cents an ounce
It takes a mature tree an entire season to produce just a gallon of maple syrup, which is why it's one of the more expensive grocery items. There are cheaper alternatives, but they contain artificial flavors and high fructose corn syrup. And when it comes to the rich, sweet maple flavor, there's nothing like the real thing.
Many brands sell maple syrup at a premium, but a higher price doesn't always mean better quality. A 33.8-ounce jug of Costco's Kirkland Signature organic maple syrup runs you $12 compared to $27.47 for 32 ounces of NOW brand at Walmart.
Costco price: $4.99 per whole chicken
Boston Market price: $8.49 per half chicken, plus two sides
Cooked rotisserie chicken makes for a quick and easy hot dinner in a pinch, but there's a price to pay for the convenience -- unless you're shopping at Costco. Members can pick up a fully cooked, hot and ready-to-serve chicken for just $4.99. Compare that price to Boston Market, where you can get just half a chicken with two sides for twice the price.
Costco sold an astonishing 101 million of its famous rotisserie chickens with the never-changing price tags in 2020 alone. That's 300,000 chickens a day.

How They're Doing It: How I'm Sticking to a Budget and Spending Less During COVID-19
Macaroni and Cheese
Costco price: 89 cents per box
Walmart price: $1.07 per box
Mac and cheese has been a go-to, no-fuss, on-the-fly dinner for decades in America -- and another bonus is that it's cheap. "Cheap," however, is a relative term. At Costco, an 18-pack of 7.25-ounce boxes of Kraft Macaroni & Cheese will run you $15.99. At Walmart, the same 18-pack is $19.30.
Don't Wait: 19 Effective Ways To Tackle Your Budget

Walmart price: 33 cents an ounce for steak seasoning
At Costco, McCormick Grill Mates Montreal steak seasoning costs $7.49 for a 29-ounce jar compared to $9.63 for the exact same weight of the exact same stuff in the exact same jar at Walmart.
Hot Dog Meal
Costco price: $1.50, including a 20-ounce drink
You don't need a Costco membership to cash in on this incredible deal at the food court. For just $1.50, you can fill up on a quarter-pound, all-beef hot dog and a 20-ounce drink (with unlimited refills). Just as with its vaunted rotisserie chicken, Costco could rake in untold millions if it would just raise the price of its famous hot dog deal by only a little bit, but it chooses not to -- for a reason.
A filling, tasty, low-budget food court incentivizes otherwise reluctant shoppers to hit the store for marathon shopping trips. In fact, the price of Costco's famous hot dog deal hasn't changed since Hebrew National -- then Costco's hot dog supplier -- set up its first cart outside a San Diego Costco in 1984. Costco switched to its own Kirkland brand in 2009, but the deal remains the same.
In 2021, you can't get a cheaper dog and a large drink without a time machine.
Costco price: 17 cents an ounce
Target price: 21 cents an ounce
The go-to breakfast for generations of kids, cereal is an American staple. Staples can be expensive -- but they don't have to be if you shop at Costco. A two-pack of classic Cheerios at 20.35 ounces each, for example, will run you $6.99 at Costco. The biggest single-item purchase you can make at Target is a one-count 18-ounce family size for $3.79
Luxury Bath Towels
Costco price: $19.99 per two-pack
Amazon price: $34.95 per two-pack
A nice bath towel can make or break your post-bathing experience, but luxury bath towels can cost a small fortune. Once again, Costco uses its buying power to drive down the price on this typically expensive item. The retailer carries Charisma Bumpy Rib bath towels, made of 100% Hygro Cotton, for just $19.99 for two. Amazon sells a two-pack for $21.99.
Costco price: 20% to 30% off face value
Most major retailers and grocery stores sell gift cards, but they aren't always sold at a discount.
The deals on gift cards at Costco can be significant. You can buy two $50 gift cards to Romano's Macaroni Grill for $74.99, for example, or four $25 gift cards to The Coffee Bean & Tea Leaf for $79.99
Costco also sells discounted gift cards for movie tickets, rounds of golf, iTunes, gym memberships and amusement parks. Whether you keep them for yourself or give them out as gifts, this is a great way to cut back on your budget without sacrificing the fun.
Over-the-Counter Allergy Medicine
Costco price: 19 cents per pill
Amazon price: 43 cents per pill
Costco has a huge selection of over-the-counter medicine, including Kirkland-brand allergy pills that are a fraction of the cost of competitors' prices. Kirkland Signature Aller-Fex costs $33.49 for 180 tablets or about 19 cents per pill. Aller-Fex ingredients are comparable to Allegra, which Amazon sells for more than twice that amount.
Costco price: 6 cents per ounce
Walmart price: 8 cents per ounce
It's been well-established that you can save money on the humans in your family by taking advantage of Costco's low prices, but you shouldn't stop there. Costco has a huge inventory of pet supplies, and classic dog bone treats offer some of the best deals around. If you opt for Costco's Kirkland brand dog biscuits, you'll pay just 6 cents per ounce. Walmart doesn't offer its own version of the same thing, but it does sell comparable Milk-Bone biscuits for a couple of cents more per ounce on 10 pounds worth.
Costco price: 38 cents per cup
Walmart price: 95 cents per cup
Just as macaroni and cheese has done for dinner, instant noodles have served as the default option for quick, cheap lunches on the fly for generations of families and college students. And as a plus, they're microwaveable when purchased in cup form for added convenience. At Costco, a 24-pack of Nissin Cup Noodles is $8.99, or 30 cents per 2.5-ounce cup.
At Walmart, a 30-pack of 2.25-ounce cups -- that's smaller cups in greater bulk -- will run you $28.60.
Costco price: 97 cents an ounce
Amazon price: $1.24 an ounce
Parents and caregivers have an abundance of choices when deciding where to buy infant formula, but this item is always cheaper at Costco. A two-pack of 34-ounce containers of Similac Pro-Sensitive formula is $69.99 at Costco.

Costco price: 6 cents per tablet
Amazon price: 8 cents per tablet

Walmart price: 61 cents per pod
One huge benefit Costco has over the competition is that its Kirkland brand features its own line of coffee pods. You can take home 120 of them for just $37.99 -- that's three pods for a buck with four cents left over to spare. A 120-pack of 8 O'Clock pods at Walmart, on the other hand, will run you $73.54 -- nearly double.
Costco price: $4.33 per pair
Amazon price: $9.99 per pair
If books are a blur but you don't need prescription lenses, a good pair of reading glasses can help bring everything into focus.

Costco price: $1.04 per ball
Amazon price: $3.33 per ball
Kirkland Signature even has its own line of golf balls -- and these are no raggedy shag balls, either. The three-piece, V2.0 urethane-covered balls have earned 4.6 stars from more than 1,400 satisfied Costco golfers -- and they cost just $24.99 for 24, which comes out to about a buck per ball. A single 12-pack of Titleist Tour Speed, on the other hand -- that's half as many balls -- will run you $39.97 on Amazon, which vouches for the deal with its "Amazon's Choice" label.
Costco price: 20 cents per ounce
Target price: 23 cents per ounce
Delicious, versatile and pricey, olive oil is the first ingredient in everything from sauteed dishes to salads, but unless you settle for the cheapest stuff on the shelf, all that flavor will cost you a pretty penny -- a few pretty pennies less, however, at Costco.

Target price: 3 cents per square foot
You can save big bucks on paper towels at Costco, thanks once again to the Kirkland Signature brand, which offers a 12-pack of rolls for $19.99. Target's Up & Up brand, too, offers its own line of paper towels. Its 12-pack of "double rolls" sounds like a comparative bargain at $14.99, but there are only 110 sheets per roll to Kirkland's 160.
Costco price: 6 cents per tablet
Amazon price: 7 cents per tablet
Advil ibuprofen tablets have been soothing everything from backaches and burn pain to headaches and hangovers for decades. If you're in pain, you'll save a lot on the relief you need by shopping at Costco, which sells 360 Advil tablets for $21.99, or about 6 cents per tablet. At Amazon, the same 360 pills cost you $23.99, or about 7 cents each -- and that's marked down from $28.79, the regular Amazon price for the same bottle.
Costco price: 75 cents each
Amazon price: 97 cents each
Costco makes kitchen cleanup quick and easy -- and cheap. A 21-pack of popular Scotch-Brite non-scratch sponges costs $20.37 at Amazon -- and that's on sale from $24.99. At Costco, however, that same 21-pack will only set you back $15.79.
