Costco vs. Sam's Club: A Practical Membership Guide for Korean Americans

If you're newly settled in the U.S., a warehouse club membership can quickly become one of your best financial decisions. Costco and Sam's Club both offer bulk groceries, household essentials, pharmacies, optical centers, and even tire services—all under one roof. The real question is which one makes more sense for your household size, location, and shopping habits.

Membership Tiers and Annual Fees

Costco offers two tiers: Gold Star at $65/year and Executive at $130/year. The Executive membership earns 2% back on most Costco purchases (up to $1,000 annually), so if your household spends around $3,250 or more per year at Costco, the reward covers the price difference. Sam's Club has Club at $50/year and Plus at $110/year. Plus members get free shipping on most online orders, extra savings at the pharmacy, a few cents off per gallon at Sam's Club fuel stations, and 2% cash back (capped at $500/year). Both clubs include one free household card for a family member.

• Costco Gold Star: $65/yr — shopping, pharmacy, gas station access
• Costco Executive: $130/yr — everything above + 2% annual reward
• Sam's Club Club: $50/yr — shopping + Scan & Go app
• Sam's Club Plus: $110/yr — free shipping + cash back + fuel discount

How to Sign Up and Practical Tips

You can join at the membership desk in any warehouse location or online at costco.com or samsclub.com. A Social Security Number is not required—a passport and a U.S. mailing address are enough to get started. If you go with Costco, consider applying for the Costco Anywhere Visa by Citi at the same time: it earns 4% on gas, 3% on dining and travel, and 2% on Costco purchases with no annual fee beyond your membership. Sam's Club's Scan & Go feature lets you scan items with your phone and skip the checkout line entirely—a genuine time-saver. For Korean American shoppers, Costco locations near Korean communities—such as those in Crenshaw (near Koreatown LA), Palisades Park (NJ), or Duluth (GA)—tend to carry a solid selection of Korean pantry staples and frozen foods. Finally, both clubs offer a full refund on your membership at any time if you're not satisfied, so there's little risk in trying one out.
