Our Recommendation
If you can only choose one:
Choose Prime if you live in an urban area, value streaming, make frequent small purchases, or don’t have access to Costco.
Choose Costco if you have a family, drive regularly, care about food quality, and can store bulk purchases.
If you can have both:
The combined $204-269/year is worth it for most households earning $50,000+. The memberships serve different purposes, and together they maximize both convenience and savings.
The Real Question
It’s not “Prime OR Costco”—it’s whether each membership earns its individual cost. For most shoppers:
Prime is worth $139 if you stream video and order monthly
Costco is worth $65-130 if you shop monthly and fill up gas each week
Calculate your own usage. For many families, the answer is both.
