When it comes to club store memberships, 28% of U.S. adults say they belong to Costco, 20% to Sam’s Club, and 6% to BJ’s Wholesale Club, according to the poll, noting that some adults belong to more than one warehouse club. 

Yet, despite the seemingly lower number of adults in households that grocery shop at club stores compared with major grocery chains, club members generally are satisfied with the clubs to which they belong, the poll data shows.

“The percentage reporting that they are ‘very or somewhat satisfied’ with the membership fee ranges from 80% to 88%, depending on the specific club to which they belong; with the price of products, 90% to 94%; with the quality of products, 91% to 97%; customer service, 88% to 96%; and trustworthiness, 93% to 99%,” SSRS notes.

Further, the poll finds that warehouse club members generally are more likely to say they are “very satisfied” with quality (54% to 69%), customer service (45% to 67%), and trustworthiness (45% to 67%) than with membership fees (38% to 44%) and the price of products (31% to 45%).

In a 2025 Mintel report, “Warehouse Club – US,” Katie Hansen, senior analyst for retail and eCommerce at Mintel, Chicago, and author of the report, notes that shoppers enjoy what club stores have to offer. 

Moreover, the Mintel report notes that consumers are loyal to their club store.

“Two-thirds of consumers say they are loyal to their preferred club store,” it states. “Memberships make for loyal, returning consumers, especially as they learn how these memberships can provide additional perks and benefits beyond monetary savings when purchasing products in bulk.”

The Mintel report also discusses how tech is expected to change what club stores offer, noting that although the stores might not always feel innovative, club stores are tapping into improving the shopping experience through scan-and-go technology and AI-enabled bots. 

“Retailers must ensure they are clearly communicating the benefits of such features to drive consumer interest and adoption,” the report states.

As for future predictions, the Mintel report suggests that warehouse clubs will evolve with technological advancements, enhancing convenience through smart shopping solutions such as scan-and-go, personalized shopping experiences and AI-driven inventory management.

“Enabled with new forms of technology, club stores will turn a focus to offering a plethora of services to consumers,” the report states. “Partnerships and experiences will become more prominent as club stores look to increase the value offering to consumers.”

Additionally, the report points to younger consumers as key for future growth.

“Looking ahead, Gen Z and millennials should be key targets, as they are most likely to have never been a member but open to joining,” it states. “Those in these groups who are members tend to value and enjoy the experience and even take pride in it.

“While value is the main priority across generations, younger consumers are looking for elevated offerings from retailers,” the report continues. “These younger generations aren’t satisfied with purely transactional shopping; they seek elevated experiences that combine convenience with elements of engagement, personalization and purpose.”

Another key point that the Mintel report highlights is that the monetary savings club stores offer across categories excite shoppers, creating a sense of savviness, and pride. 

“Nearly half (47%) even use/wear store brand items to show their affinity,” the report states. “This creates a sense of loyalty with club stores, something that is hard to establish, and maintain, in the retail industry today.”

Ultimately, according to Mintel’s Hansen, “The future lies in improving memberships with better services and unique experiences, offering even more value to customers.”
