There are times when you think your question may be silly, so you don't ask. Making that mistake about Costco can lead you to miss out on some great opportunities to save money.
Many people don't know if Costco's products and prices are just hype or how the retailer helps shoppers save money on groceries.
Here are answers to some questions you probably have about Costco but are too embarrassed to ask.
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 12 months from account opening on purchases and qualifying balance transfers (then 19.24%, 24.24%, or 29.24% 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.

Do people really save at Costco?

Costco offers the best shopping hacks compared to its competitors. The retailer offers products priced lower than local competitors, as well as discounted travel, tires, prescription glasses, and more.
Coffee, eggs, yogurt, toilet paper, and many other items are typically less expensive at Costco. Gas is often much more affordable, too.
The catch? You'll have to pay an annual membership fee to access those low prices and discounts.
Can I shop if I forgot my Costco card?
/images/2023/02/01/hand_holding_a_costco_membership_card_on_a_cart.jpg)
You have to be a Costco member to shop at Costco, but if you don't have your physical card with you, you can stop at the customer service desk for a temporary replacement.
You'll need to provide some type of identification so the team can locate your membership status. You can also access a digital membership card on the Costco app.
Can I try Costco before getting a membership?

Are you worried about spending money on a membership only to find out you don't want to buy anything there?
Just visit the customer service desk at a Costco warehouse to learn more about membership and get your questions answered.
While you will have to be a member to make a purchase, you can use the Costco pharmacy or enjoy a meal or snack in the food court without a membership.
Can I change my membership card photo?

If you don't like your Costco membership card photo for any reason, just stop by the customer service desk and get a replacement. It only takes a moment, and you'll be automatically issued a new card.
Is there a discount for teachers and the military?

Unfortunately, Costco doesn't offer free or discounted memberships to teachers or members of the military. However, both groups can receive a $20 Costco Shop Card when they sign up for a Costco membership.

Costco encourages its shoppers to try new things, which is why it lets you bring back anything you bought and didn't like.
There are some product-specific limitations, but the customer service team at Costco is nearly always willing to help. They offer a 100% satisfaction guarantee and stand behind it. You can even get a refund of your Costco membership fee.
Do I need my Costco card for gas?

It's not possible to pump gas from the Costco pumps without your card. But that doesn't mean you can't fill up if you left your card at home.
You can either use your Costco digital membership card on your phone or stop at the service desk for a temporary card.

What's up with the toilet paper?
/images/2023/02/01/charmin_ultra_soft_toilet_paper.jpg)
Costco sells about one billion rolls of toilet paper every year, amounting to $400 million in annual bath tissue sales. So why are people so obsessed with it?
Good marketing helps with getting people excited about something as simple as toilet paper, but it's also typically priced well.
The quality of Costco's store brand Kirkland Signature competes with some of the leading brands. You don't have to get the cheap stuff to keep more money in your wallet, but you do have to buy in bulk.
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.
Can someone else use my Costco card?
/images/2023/02/01/costco_membership_card.jpg)
Although your friends can't use your Costco card to make purchases, you can buy them a Costco Shop Card that they can use.
The Costco Shop Card is much like a gift certificate, allowing the person who has it to use it to buy just about anything they want at any Costco location.
Only Costco members can purchase this card, though. So, if you want to buy a gift card to help your son or daughter buy gas, you can buy them a Shop Card and let them purchase on their own.
Can I bring my mom to Costco?
/images/2023/02/01/grateful_adult_son_hugging_senior_mother.jpg)
Members can bring others with them to shop at Costco. If you want to show your mom all of the great deals and savings options out there, this is a great way to do it.
Just remember that she can't go without you or another member. She also can't use your card and misrepresent herself as you.
You'll need to make any purchases for her using your membership card since she can't buy anything without a Costco card.
How fresh is the seafood?
/images/2022/12/22/wild_sockeye_salmon_fillet.jpg)
Costco carries the best quality fresh and frozen seafood, along with wild-caught fish, even at their landlocked warehouses. Team members can even tell you when the fish you're looking at was caught.
Costco has direct connections with seafood processors who buy directly from the docks. This helps to minimize the number of "middlemen" in the process and gets products to stores faster.
Does Costco deliver appliances or furniture?
/images/2022/12/29/costco_wholesale_truck_driving_on_the_freeway.jpg)
Costco offers a full delivery service to meet the needs of its customers. That includes in-home delivery of items like freezers, washers, dryers, patio furniture, and even large mattresses.
The retailer will also handle the installation of some items, including wall ovens, gas appliances, and dishwashers. You can make arrangements in advance to manage the whole process.
Quick tips: How to save on your grocery bill
/images/2024/07/10/family-shopping-at-grocery-store.jpeg)
Grocery shopping doesn't have to break the bank when you use the right strategies. Here are three quick tips for reducing food expenses:
- Buy store brands instead of name brands whenever possible.
- Always make sure to compare unit prices, not just sticker prices.
- Join your store's loyalty program so you don’t miss out on member discounts.
Even though something like choosing coupons in your grocery store app can feel like an annoying task, the savings can really add up.
Bottom line

If you don't want to go to the customer service desk or just aren't sure about asking another member, you can use the chat feature on the company's website. It's a pain-free way to get your questions answered.
And if you don't want to leave your house, you can buy many of the items you need online using your Costco membership card. Just remember to bring your best cash back credit cards for extra savings.
