From cheap rotisserie chickens to bulk toilet paper to great discounts on gas and alcohol, Costco is a treasure trove for frugal shoppers.

Although you could save money just by doing your regular shopping at Costco, the potential savings don’t end there—and you don’t have to be a member to take advantage of all these Costco shopping hacks.

There are a number of strategies you can use, whether you’re a member or not, to maximize your savings at the popular wholesale club.

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.

Look for prices ending in .97

Looking at Costco price tags can give you clues as to whether a product is an especially good deal. For example, products with prices ending in .97 indicate that the item is on clearance.

If you find a product with a price ending in .89, .79, .69, .59, or .49, this may indicate that the manufacturer is providing a special price to Costco stores, so you may be getting a better deal than you would get elsewhere. It could also mean they’re testing a new product. 

That said, even if you see these numbers, savvy shoppers still compare prices to ensure they are getting a deal.

Buy Kirkland brand products

Kirkland products are often manufactured by well-known brands, which means you can get quality products in different packaging at a lower price. 

For example, Kirkland coffee varieties are made by Starbucks, and Kirkland Signature Diapers are manufactured by Kimberly-Clark, which makes Huggies brand diapers.

Fuel up

Costco offers competitive prices on gas for members. If you’re located near a Costco gas station, you could save a decent chunk of change just by filling up there. 

However, if you’re purchasing the membership only for the purpose of getting cheap gas, do the math to make sure you drive enough to offset the cost of the membership. 

You shouldn’t assume Costco offers the lowest price in your area, either. Run a search on GasBuddy to see which nearby gas stations can offer you the lowest prices before you decide where to fuel up.

Stop overpaying when you shop online at Costco

Shopping online has its perks. It's super convenient, but it can be time consuming to find the best deals. Instead of hunting for coupon codes (that don't always work!) and opening tons of browser tabs comparing prices, you can try Capital One Shopping.

Capital One Shopping makes saving money effortless. Just add the browser extension and when you check out, it'll scour the internet for coupon codes to help you save cash. And before you check out at 25+ major retailers, Capital One Shopping will notify you with a friendly pop-up if the item you're buying is available cheaper somewhere else.

Capital One Shopping is free to use and won't show you ads. Add it today and stop overpaying!1

Use the right credit card

Another easy Costco hack that all shoppers can take advantage of is the potential to earn cash back on their purchases.

Costco only accepts Visa cards when you’re shopping in person, but there's a high potential to earn cash back depending on which card you use.

Buy discounted gift cards

Costco offers a variety of discounted gift cards you can use to save money at other retailers, and some of the deals are available to non-members. 

For example, currently, you can get a $100 PlayStation or Xbox gift card for only $89.99 or $60 worth of Krispy Kreme gift cards for only $44.99. If you snag one of these deals for a retailer you shop at anyway, it’s essentially like getting free money.

Get your rotisserie chicken

Even as other stores raise their prices, Costco rotisserie chickens remain $4.99, a deal that attracts new members and gets people into the store on a regular basis. 

Costco is even willing to lose money on its rotisserie chickens because the retailer realizes how much business the deal attracts. People come for the chicken and end up filling their carts with other items that offset the store’s loss.

Compare prices to the grocery store

If you’re wondering how to save money on groceries, shopping at Costco isn’t the only answer. In fact, you might find that some products are cheaper elsewhere. 

Even if you have a Costco membership, you should compare prices for items on your shopping list with other stores in the area.

Get money back from sales

Costco has a generous price adjustment policy. If you buy an item on Costco.com and the price drops within 30 days, you can request a price adjustment online. 

If you buy an item in-store and it goes on sale within 30 days, you’ll need to bring your receipt to the membership counter at that Costco warehouse location in order to get a refund for the difference.

Use coupons and rebates

Costco frequently sends promotional offers to members who are email subscribers. Make sure you sign up to get the news and special offers for your local store. 

You can stack these offers with savings from rebate apps such as Ibotta, which allows you to earn money from your Costco receipt or get cash back when you use a linked credit card. 

For example, right now you can get $2 to $7 back on most bottles of alcohol from Costco when you shop with Ibotta.

Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more.

Whether or not you’re a new homeowner, a home warranty from Choice Home Warranty could pick up the slack where insurance falls short and protect you against surprise expenses. If a covered system in your home breaks, you can call their hotline 24/7 to get it repaired.

For a limited time, you can get your first month free with a Single Payment home warranty plan.

Look for the asterisk

Items marked with an asterisk in the upper right-hand corner of the price tag are going out of stock. Once the limited supply sells out, the item won’t be reordered. 

This doesn’t necessarily mean you’re getting a discount, but you won’t see the price drop any lower if you wait. If it’s an item you have your heart set on, that asterisk is your cue to buy now while you still can.

Get an eye exam

You don’t have to be a member to use Costco Optical services, though you’ll get some additional discounts when you order optical products online if you do have a membership card. 

But if you don’t have vision insurance, Costco could be your best bet for a low price on your annual exam. 

Prices vary depending on where you live but are usually around $70. You can also find great deals on sunglasses and contact lenses at the wholesale club.

Buy alcohol for a great price

Costco has some very appealing deals on liquor, beer, and wine, and you don’t necessarily have to be a member to snag the discounts. 

In at least a dozen states, local laws preclude wholesale clubs from selling alcohol only to members, so depending on where you live, you may be able to walk into Costco and stock up on inexpensive wine without a membership. 

Call the store before you go to make sure you’ll have access to alcohol as a non-member.

Fill your prescription

Costco has a pharmacy that is open to non-members in some states. And you can get some pretty sweet deals on prescriptions if you fill them there. 

For example, the popular antibiotic azithromycin fills for around $8 at Costco, about half the average price at GoodRx and about a quarter of the retail price.

You might not necessarily get the lowest price at Costco, depending on the prescription you need to fill, what your insurance covers, and what other stores in the area are offering, so check GoodRx for the lowest prices on all your prescriptions.

Shop on Instacart

As a Costco member, you can get same-day delivery from Costco via Instacart, but you’ll pay additional delivery and service fees. 

Non-members can order through Instacart as well — making this the only way to access most of Costco’s food inventory as a non-member — but they’ll pay a higher price.

Consumer Reports found that members pay about 31% more for their items delivered than they would in-store, and non-members pay a bit more than that for delivery, but Costco’s program is still a good deal for home delivery.

Get car and home insurance

Costco members can get special discounts, in addition to traditional discounts, on home and car insurance with CONNECT by American Family Insurance. 

There are also exclusive member benefits such as roadside assistance and lifetime renewability for Costco members. 

Costco members who saved on car insurance by switching coverage reported an average of more than $600 in savings in their first year. That more than offsets the cost of a membership.

Get exclusive travel discounts

Did you know Costco can save you money on travel? Not only can Costco members find airline gift cards at reduced rates, but they can also book vacation packages, hotels, flights, and rental cars directly through Costco for exclusive member discounts. 

It’s an especially great place to save money on rental cars, and there are no cancellation fees. Your rental also includes an additional driver at no cost.

Stock up on the right items

As you compare prices with other stores, you’ll find that certain items at Costco are offered at particularly low prices. If you stock up on those items whenever you visit Costco, you could save a pretty penny. 

Pro tip: Make sure you take advantage of all of the best Costco hacks so that you can save money and enjoy the best that the warehouse retailer has to offer. 

Bottom line
