14 Costco Hacks Only the Pros Know (You’re Doing #9 Wrong)

I’m a Costco superfan. I love writing about Costco and giving tips to warehouse shoppers based on what I’ve learned.

But to be honest, I don’t always follow my own rules. Sure, I have my favorite Costco shopping hacks , but some would only save me money if I actually followed them.

Want to know my secrets? Here is what I’ve learned over hundreds of Costco trips.

Costco Secrets: 7 genius hacks all Costco shoppers should know

1. Change your shopping habits based on your needs

As I started to write this article, I realized I've made hundreds of successful shopping trips to Costco, so I almost have to share the wisdom I've acquired to help you save money on groceries .

I started as a Costco member when I was single and living in a studio apartment in New York City, and I’m a Costco member now in a house with my family.

Some things on my list have changed, like the Goldfish crackers I added when I had kids. But some things have stayed the same, like that pack of toilet paper. I’m not kidding when I say it’s been a staple in my Costco cart for decades.

2. Stock up on staples

As I said, Costco is a great place to pick up non-perishable staples like paper goods, pantry items, frozen foods, and more.

Despite my changing needs over the years, I’ve always kept the bottom of my cart clear to have room for a pack of toilet paper. It’s my staple of staples at Costco.

Pasta and pasta sauce have also been on my list for years because they’re the perfect kitchen staples for dinner after a long day.

3. Buy Kirkland Signature

You may be surprised to find that Costco’s in-store brand is just as good as its name-brand competition and better in some cases.

For example, I’m still working through a box of Kirkland Signature trash bags that were cheaper than the name-brand version, and I’ve never had an issue with the quality.

4. Don't get gift cards

Gift cards are a great pick-up at Costco if you’re trying to save money. Costco carries a variety of cards, and you can sometimes pay less than the face value of the card. For example, if you’re a Krispy Kreme fan, you can buy $60 worth of cards for $44.99.

But I either don’t have a restaurant nearby that is covered by Costco’s gift cards, or I do but always forget to bring the cards.

If you're like me, feel free to skip the gift cards. There’s nothing wrong with passing up a deal if you won’t be taking advantage of it.

5. Return clothing

I used to get so frustrated with Costco’s lack of dressing rooms. The store would have cute seasonal shirts or new workout gear, but I would never buy any because I couldn’t try it on. I’ve now embraced buying clothes and trying them on at home.

One of the great things about Costco is its generous return policy. So if I take something home and it doesn’t fit, it’s no big deal. I just store it until I’m ready to go back to Costco and return it then.

And I don’t have to worry about how far in the future that may be. Costco will take items back without a receipt after any amount of time in most cases.

6. Skip books and DVDs

One of my goals for this year is to bring less stuff into my house. There’s so much clutter that I’m trying to sort through and either donate or sell.

One of my favorite spots at Costco used to be the books and movies section. But I skip that section now in favor of using my library card.

My local library has a great selection of books and DVDs, making it easy to avoid spending money on them. Plus, I return them to the library when I’m done so I don’t add to the clutter in my house.

7. Watch the Costco sales flyer

Costco’s monthly flyers can have some great deals. Sometimes, a deal is so good that I’ll add an item to my list that I would normally skip.

For example, last month, I broke my rule of choosing the Kirkland Signature brand when possible because the name brand was on sale and more affordable. I also stocked up on toothpaste even though we’re still working on our previous pack from Costco.

Also, I like to try new snacks (or snacks I haven’t picked up in a while) if I see a deal on them that can save some extra cash.

8. Buy produce

One piece of advice I often give is to think twice about buying any produce in bulk. That's because, unlike pantry items, it’s easy to buy a bulk version of a produce item and find it goes bad before you finish it.

But my family loves eating apples, pears, strawberries, and blueberries. So yes, I do buy produce in bulk at Costco. And yes, it gets finished way before the expiration date, so I rarely, if ever, have to throw out rotting produce.

9. Don't fill up your gas tank

If you’re trying to save money on gas , Costco’s gas stations can be a great solution to help you keep cash in your pocket.

But my Costco regularly has lines at its gas station, and I dread sitting there waiting to fill up after a long shopping trip with frozen items defrosting in my trunk.

I also don’t live that close to a Costco, so it’s out of my way to fill up there, negating any savings I may get by driving there for gas. This may be the case for you, too.

10. The hot dog isn’t worth staying for

One of Costco’s most famous deals is the $1.50 hot-dog-and-drink combo at the food court. In fact, it’s so famous that Costco’s CEO had to promise his predecessor he wouldn’t increase the price of the deal.

But after pushing a heavy cart through the aisles of Costco, I just want to get that stuff in my car and head home, so I rarely take advantage of that deal.

Sometimes I consider it or think a quick stop for a churro wouldn’t be a bad idea, but my desire to go home usually wins out.

11. Skip good deals occasionally

There have been times when I’ve bought a bulk version of something at Costco and it took up space in my pantry for a year before I finally pitched it. Other times, it took way too long to use up the bulk version of an item.

So I’ve learned to accept that just because Costco has a good deal doesn’t mean it’s a good deal for me. There’s nothing wrong with walking by and leaving something on the shelf.

12. Always make room for a rotisserie chicken

I may have plenty of dinner options in my cart, like the Kirkland Signature Atlantic Farmed Atlantic Salmon or the four-pack of frozen cheese pizzas to which we add our favorite toppings at home.

But even with all those options, I still grab a rotisserie chicken. It’s cheap and can be an easy dinner option for that night or another night.

I’ve also taken the rotisserie chicken apart at home to use as an ingredient in other dishes, like my homemade chicken salad recipe.

13. Browse Costco’s wine selection

Costco is great for wine shoppers like me. The store has a wide selection of wine, and I don’t mind taking a chance sometimes because of Costco’s affordable options.

I don’t have an expensive and extensive wine collection. I know which types I like, and I like bottles that cost less than $15.

I’ve even picked up a few of the retailer’s Kirkland Signature wines. I enjoy them and look for them every time I’m at the store.

14. Stick with the Gold Star card

Costco has two membership options: A Gold Star card for $65 annually or an Executive card for $130 annually.

The Executive card has some additional benefits, with the biggest being the 2% annual reward.

There were a few years when I took advantage of the extra savings, like when buying diapers for my kids. But then there were a few years when I spent less than $3,000 annually at Costco, so the benefit didn’t balance out compared to the extra cost of the card.

It was a good reminder to double-check my Costco spending and remember that the upgrade isn’t always better when I consider my annual spending.

Bottom line

The great thing about Costco is there are plenty of ways to avoid wasting money , so tailor these tips and tricks to what fits into your spending habits and budget.

You may want to test them out the next time you head to the warehouse retailer or perhaps review your Costco run while enjoying the $1.50 hot-dog-and-drink deal to figure out where to save next time.

Money tips that can work for everyone

No matter what your bank account balance is, there's always an opportunity to optimize and improve your finances. Here's a quick checklist of things you can look at today.

Focus on paying off your debt . Debt can hold you back from making progress with your overall financial well-being. Aside from cutting expenses, there are tools that can help you pay off debt faster like balance transfer credit cards and debt counseling.

Earning extra income can give you breathing room. If finances are tight, earning some extra money to supplement your income can make a huge difference. A new job is one option to consider, but if you're not ready to make a big change or already retired, a part-time side job could be a better choice.

Cut your expenses. It sounds painful and so not fun, but it doesn't have to be. Take a look at your biggest expenses because that's where you'll probably find the biggest savings. For example, auto insurance rates have been soaring so shopping around for a new insurance company can be the fastest way to cut your bill. Also, look for ways to cut your grocery bill (despite rising inflation).
