The move comes as Costco has recently cracked down on non-member buyers, the New York Post reports.

Earlier this month, the company even announced it would stop sharing its membership cards.

In his video, Mr. Castillo, who lives in California, explains that his father has a “Gold Star” membership card that costs 80 Canadian dollars.

This is Costco’s lowest membership level, allowing for a total of two authorized users.

“When I went to university, my father allowed me to be a user instead of my mother,” explains the young man in his video, which has been viewed more than three million times.

Mr. Castillo explains that his mother has had no problems shopping at Costco for years.

But when her mother scanned the card at the checkout about two months ago, “employees rushed in” and asked for her ID.

“After confirming it wasn’t her card, they told her never to go back to that store,” he explained in his TikTok video.

When asked by Fox Business, a spokesman for Costco Wholesale elaborated on the situation in a statement: “Costco is able to keep its prices as low as possible because membership fees help offset our operating costs.”

“Costco’s membership policies have not changed. We always asked for membership cards at our tills when checking out,” the press release continues.

“Our membership policy states that our membership cards are non-transferable, and since the launch of our self-checkouts, we have noticed that non-member customers are using membership cards that do not belong to them.”

The Company believes that it is unfair for non-members to receive the same benefits and pricing as members who pay an annual subscription to receive benefits related to their purchases.

“Since we already ask for the membership card at the checkout, we now ask that you show the membership card with your photo at our self-service checkouts,” said the Costco spokesman.

“If there is no photo on the membership card, we ask for photo ID,” he said.

The users of the TikTok platform were divided on this issue.

Some think Costco should make adding authorized users to a card easier, while others think the company should expand membership to all residents of the same address.

Mr. Castillo told Fox Business that he and his family did not hold Costco responsible for enforcing its policies.

However, they believe the retailer could do more to clarify its membership terms.

“My husband is often on business trips and we only have to go to Costco once a month to buy our essential household products, groceries and toiletries,” Mr. Castillo’s mother said in a statement sent to Fox Business.

“We should be able to share this membership because we both benefit from these products and share the bills,” she says.

However, her son concedes that “technically” his mother was indeed wrong and that she had “already received a warning” in the past that she “probably forgot”.

“We have no animosity towards Costco,” he says.

Although Costco’s rules may seem unclear, the company’s website clearly states that the Gold Star membership card, which Mr. Castillo’s father claims to have, allows a maximum of two users.
