Costco, Sam's Club and BJ's Open New Stores as Membership Soars

Warehouse retailers like Costco, Sam's Club, and BJ's are facing a problem many businesses would envy: how to manage the overwhelming crowds of shoppers flocking to their stores. On recent earnings calls, executives found themselves answering questions about packed parking lots and crowded aisles—a clear sign of their booming popularity.

These membership-based clubs have become retail destinations by offering more than just bulk bargains. Shoppers are drawn to eye-catching merchandise, affordable prepared meals, and faster online ordering options that make the warehouse experience more convenient than ever.

The expansion continues as all three major players open new locations across the country, betting that today's economic climate has more consumers looking for value and savings. With membership numbers climbing, it appears shoppers are voting with their wallets—and apparently, their cars are voting with their parking spots.
