Costco can get you great deals on food, home goods, and more. One of the best Costco hacks is to wait until items go on sale, so you can increase your savings.

However, not every Costco favorite gets marked down for extra discounts and deals throughout the year, no matter how much you wish it would.

Check out some of these products that annoyingly never go on sale at Costco.

Earn 2% cash rewards at grocery stores and Costco

The Wells Fargo Active Cash® Card(Rates and fees) is a powerful rewards card that allows you to earn unlimited 2% cash rewards on purchases — including on groceries, even at warehouse stores like Costco.

New cardholders can also earn a one-time cash rewards bonus — $200 cash rewards bonus after spending $500 in purchases in the first 3 months!

If you’re looking for a powerful rewards card that offers an extended intro APR period, look no further, the Wells Fargo Active Cash® Card checks that box too!

This card also offers an intro APR of 0% for 15 months from account opening on purchases and qualifying balance transfers (then 20.24%, 25.24%, or 29.99% Variable). Which is great for someone who wants a break from high interest rates, while still earning rewards.

The best part? There's no annual fee.

Kirkland Signature Colombian Cold Brew Coffee

Costco’s Kirkland Signature store brand offers some great options, including Kirkland Signature Colombian Cold Brew Coffee, which costs $18.12.

But Costco never seems to put these cans on sale. "I always have two cases on hand and they’re never on sale,” laments Reddit user GlitteringPause8.

Sensodyne Advanced Whitening Toothpaste

You can pick up four tubes of Sensodyne Advanced Whitening Toothpaste for $31.99, but don’t expect that price to go down.

Reddit user mtnlady has been waiting for this product to go on sale, but says it’s been a while since there was a discount.

Cadet Bully Sticks

Don’t forget about your pets when you shop at Costco: Cadet Bully Treats sell for $49.13 for a 12-pack.

However, Reddit users complain that the price has risen a lot compared to recent years, and sales remain few and far between.

Staples such as eggs, milk, and bottled water rarely go on sale at Costco, so you may want to take advantage of a price break if you see one.

“I've never seen the milk on sale but it's the best milk in the whole area, so I don't mind,” said Redditor CynthiaMWD.

Kirkland Signature Flex-Tech Kitchen Trash Bags

You’ll never run out of trash bags when you buy a 200-count box of Kirkland Signature Flex-Tech Kitchen Trash Bags for $19.64.

Although these rarely go on sale, folks on Reddit don’t seem to mind, as some say it takes them more than a year to get through a box.

Costco membership

Many shoppers view a Costco membership as the ultimate bargain. It costs $60 for a Gold Star membership or $120 for an Executive membership.

But don’t expect a discount on that membership fee anytime soon. In fact, the last time Costco raised membership fees was in 2017, so a price hike could be on the way.

Kirkland Signature Peanut Butter Filled Pretzel Nuggets

Costco has great snack options, but some of them are more likely to go on sale than others.

Kirkland Signature Peanut Butter Filled Pretzel Nuggets cost $11.69 but rarely get marked down. Reddit user originaw has seen them on sale before, but says it’s been more than a year since they were marked down.

Kirkland Signature Farmed Atlantic Salmon

Kirkland Signature Farmed Atlantic Salmon comes in individually wrapped packs, making it easy to store them. However, a bag can cost $40.94 for 3 pounds of salmon.

Reddit user rockysalmon did once see frozen salmon on sale at Costco. “I’ve never stocked up on something as hard as I did then,” rockysalmon says.

Costco has plenty of options when it comes to sodas, but you may be better off watching for deals at your local grocery store. You could save more money there than trying to get a deal at Costco.

Reddit user droid_mike says Costco has terrible deals on sodas, and Reddit user dougielou prefers going to Target, saying the retailer has better prices.

Kirkland Signature Nature's Domain Salmon & Sweet Potato Formula Dog Food

It can be tough to feed hungry dogs on a budget. Costco has dog owners covered with its Kirkland Signature Nature's Domain Salmon & Sweet Potato Formula Dog Food for $46.55 for a 35-pound bag.

However, it rarely goes on sale. Reddit user bygtopp has been a Costco employee for more than a decade and has never seen it go on sale.

Hot dogs

One of the best deals if you want to keep more cash in your wallet is the $1.50 hot-dog-and-soda deal at the Costco Food Court. In fact, Costco executives have repeatedly vowed not to raise the price.

That may be why some Redditers have jokingly lamented that the hot dog deal is always the same. Another Reddit user has pointed out that the hot dogs are technically always a good deal, so perhaps Costco doesn’t have to worry about putting them on sale.

Bottom line

Costco is a great option if you’re trying to save money on groceries, but some deals are better than others when it comes to buying items on sale.

Fortunately, there are other ways to save, such as using one of the best cash back credit cards when you shop at Costco so you can earn extra perks.
