Costco offers more than just big packs and free samples. With the right tips and tricks, you can save money, shop faster, and find hidden deals most people miss. Here are 30 easy Costco secrets to make the most of your membership.
The “Treasure Hunt” Trick
Costco intentionally relocates products so you have to look for them. While they call it a “treasure hunt,” it’s also a way to get you to notice (and buy) more things as you browse.
What’s on the Shelf Is All There Is
Costco is a true warehouses since there’s no hidden stock in the back. If it’s not on the shelf, it’s gone for now. Check back later; it will likely be restocked soon.
No Manufacturer Coupons
Costco doesn’t accept manufacturer coupons or negotiate prices. To save extra, stick to the warehouse savings books and take advantage of Costco’s own deals.
Costco Even Helps with Caskets
Costco sells steel caskets starting around $950 and ships to most states. It’s an example of the unexpected perks members can take advantage of.
Order Pizza Early
On busy days, fresh pizzas can take 20–25 minutes. Place your order before you start shopping so it’s ready when you’re done.
Low Markups on Everything
Most stores mark up prices heavily, but Costco keeps the markup low, usually around 10–13%, so you’re paying close to what the store paid for the items.
Pick Kirkland Products Carefully
Kirkland items are usually high quality and affordable, but not all are winners. Safe bets include bacon and maple syrup, while coffee and dishwasher packs have been less universally favored.
Watch the Markdown Date
Some prices have a small date under the last digit, this signals when an item was last marked down. Use it to decide whether to buy now or wait for another discount.
Skip the Soda at Costco
Costco soda isn’t a bad deal, but local grocery sales, especially around holidays, can be cheaper. Buy in bulk during those sales for the best long-term value.
Tire Deals Rotate Monthly
Costco rotates tire brand sales each month, so waiting can get you a better deal on your preferred brand. Plus, their service department handles flats, rotations, and pressure checks for the life of the tires.
Follow the Insider Sources
Long-time employees and insiders share Costco tips on sites like Reddit and CostcoInsider. Tapping into these networks gives you early access to deals and expert shopping advice.
Generous Return Policy (Mostly)
Most Costco products can be returned anytime, though big-ticket items like TVs and appliances have a 90-day window. Exceptions include alcohol, tobacco, high-value diamonds, and caskets, which are mostly final sales.
Kirkland Makes Up 1 in 5 Products
About 20% of Costco’s inventory is Kirkland Signature, from food to home goods. Many items rival national brands and can save you money, but always compare quality too.
Bulk Isn’t Always Better
Buying in bulk can save money, but only if you use it before it spoils. Short-shelf-life items like cleaners, cereal, and skincare can end up costing more in the long run.
Score Low-Priced Organic Foods
Costco offers a variety of organic products like produce, oils, and beverages at a lower unit price than traditional grocery stores. Buying organic here can be a surprisingly good deal.
Buy a Car Through Costco
Costco members can use the Costco Auto Program to get pre-negotiated prices on new and certified pre-owned vehicles. Members also save 15% on parts and services at participating service centers.
Membership Refunds Are Possible
If you’re not happy with your Costco membership, customer service can refund your annual fee, no questions asked. It’s part of their famously customer-friendly policies.
Use Any Credit Card Online
While Costco stores only accept a few credit cards, you can use any credit card on Costco.com. Some items are still cheaper in-store, but online shopping gives you more payment flexibility.
Ask for a Beef Chub
A “chub” is a tube of ground beef that’s cheaper than the standard packaged trays. Ask the deli to package it this way and save on ground beef.
Shop the Center First
While Costco doesn’t systematically place higher markups in the front, the best deals are often found deeper in the store, especially in the “center court.” So start in the middle and work your way back.
Bring Non-Members with a Cash Card
You can bring two guests for free, but if you load a Costco Cash Card, anyone can shop with it even without a membership. It’s a handy way to share access.
Listen for the Chicken Bell
When you hear a bell at the deli, it means a fresh batch of rotisserie chickens is out. They sell fast, so catch the bell to grab one or wait for the next round!
Rotisserie Chickens Are Still a Steal
Costco’s $4.99 rotisserie chickens haven’t shrunk, and they’re not loaded with fillers. They’re big, seasoned, and free of preservatives, MSG, and artificial colors making them a bargain compared to competitors.
Decode the Price Tags
Most prices end in .9, but special codes mean extra deals: .97 is clearance, while .00 or .88 means a manager marked it down, often for limited stock or minor imperfections.
Missed a Sale? You Can Still Save
If something you bought on Costco.com drops in price within 30 days, you can request a refund for the difference. Some warehouses even do this for in-store purchases. Just check at the membership counter.
Knock for Help in the Deli
If you don’t see a deli worker out front, you can knock on the department door. The staff will gladly come out to answer your questions or help with special requests.
Order Party Platters Ahead
Costco usually has plenty of party platters ready, but if you know you’ll need a big order, they appreciate a heads-up. Calling the day before helps them stock up so you get what you need without wiping out the supply.
Best-Sellers Stay Put
If an item sells really well in one spot, Costco won’t move it. Hot sellers get to stay where they are, making them easier to find again and again.
Watch for the Asterisk
An asterisk on a price tag means that item won’t be restocked at that location. It may return later, but if it’s a favorite, now’s the time to grab it.
Almost Everything Goes on Sale
At Costco, most items will eventually get a discount. If you can wait a bit, it often pays to hold off and snag it when it goes on sale. But this tip might not include staples like milk, eggs, and rotisserie chicken because they’re already priced aggressively.
