Costco shopping rules

The warehouse club giant offers competitive prices on everything from groceries to gardening products to electronics. And your Costco membership also gives you access to competitively priced travel packages, home services, and tires. Costco has 12 shopping rules that you need to follow if you want to buy goods at bargain prices at Costco shopping paradise.

You must bring a Costco membership card

Costco is a membership-only store, with a starting cost of at least $60 per year. Your membership card is more than just a piece of plastic with your name on it. It’s your passport to incredible deals. You will be asked to present your membership card when entering Costco, at the checkout counter, and sometimes on your way out. If you’re worried about keeping track of another card in your wallet, there’s no need for concern. Costco has you covered with the Costco app, where you can proudly display a digital version of your membership card.

Your membership card should have a photo on it

When you join Costco, you must have a photo on your membership card. If you apply in-store, they’ll take your picture and print it on the back of the card. If you apply online, you might be able to upload your own photo.

It may seem excessive, but it’s to ensure that only you can use your card for discounts. It’s a way to show you’re a member of the Costco community and ready to enjoy the savings.

If your card lacks a photo, you’ll need to show an official photo ID, like a passport or a government-issued ID from the U.S., Puerto Rico, or Canada.

You are not allowed to lend your membership card to someone else

This rule of Costco ensures that Costco members have paid their monthly fees in full before they can use their membership card to buy bargain products. In addition, there is a way for family members to comfortably shop at Costco: each Costco member can issue an additional membership card to their relatives and family members. Thus, they can use the benefits of shopping at Costco without violating any rules.

You cannot pay with someone else credit or debit card

The name on the payment card must match the name on the Costco membership card. This rule might seem like a bummer, but it’s part of what keeps Costco so cheap — only members can buy from it.

Abusing the return policy may result in your membership being revoked

You can learn more about Costco’s great return policy here. If you purchase a product and later feel it is no longer suitable, you can return the product that meets the conditions. Some of the only rules are that diamonds must be returned within 48 hours with proof of purchase, some electronics must be returned within 90 days, and you cannot return alcohol and cigarettes.

You must wear a mask and shoes all the time

There are some rules that can be considered common sense, such as when entering Costco customers should wear formal clothes, it is better to wear some clothes on your upper and lower limbs.

Animals aren’t allowed

Animals can cause chaos and danger when passing through the shelves, so the law at Costco does not allow animal owners to bring them inside.

You can’t carry weapons in Costco

This rule is in place to help keep employees and shoppers safe. Costco believes it is not necessary to carry firearms in its warehouses. Because this is a private members club and not a public space, the club has the right to enforce its own rules, even if they differ from state law.

You can bring guests, but they can’t buy anything

You might be excited to learn that you can bring two guests to Costco with you. They can throw a few items into your cart if you’re willing to put them on your tab, but they can’t buy anything themselves without a membership card. So, as long as everyone’s on the same page, it’s a great experience, but don’t let anyone get caught at the register without a membership card.

Costco doesn’t accept coupons other than ones it distributes

Costco offers the most competitive wholesale prices right from the start without requiring any extra effort. It also distributes its own coupons and deals to members, so they don’t feel the need to accept manufacturer coupons.

Primary members must be over 18

Members over 18 years old will ensure to understand and understand Costco’s policies and rules. In addition, customers under 18 years old coming to Costco should be accompanied by an adult to ensure store security.

You have to show your receipt when you leave

Costco focuses on keeping things legal and making sure you get exactly what you paid for. According to Costco, it’s all about making sure your purchase is properly paid for by the cashier and that you’re being charged correctly for what you bought. However, this is Costco’s polite way of saying they’re checking to see if people are walking out with items they haven’t paid for – whether accidentally or on purpose.
