The affiliate marketing world is packed with options, but let’s be real—few names carry the trust and hype of Costco. With over 120 million members worldwide (yep, that’s like the population of a whole country!) and a rep for selling great stuff at crazy-good prices, their affiliate program is a golden chance for anyone who wants to earn money online while recommending something people already love.
What Is the Costco Affiliate Program?
Think of Costco’s affiliate program like a “members-only” money-making club. Instead of just pushing random products like most affiliate gigs, this one is all about getting people to sign up for Costco memberships. Why? Because Costco’s secret sauce isn’t just selling giant packs of snacks—it’s turning shoppers into long-term members who keep coming back.
They run the whole thing through Commission Junction (CJ Affiliate), which basically gives you the tools—tracking links, banners, reports—to make promoting easier. If your audience loves bulk shopping, saving big as a family, or just stretching their money further, this program is built for you.
Commission Structure: Understanding Your Earnings Potential
Membership Commission Rates
Here’s where the money magic happens. The Costco affiliate program pays flat-rate commissions for new memberships:
- Gold Star Membership: $3 for every person who signs up
- Executive Membership: $6 per new member
Think of it like getting paid just for introducing your friends to a club they’ll love—easy, right?
Product Purchase Commissions
It doesn’t stop at memberships. You can also earn a cut on certain product sales:
- General Products: 3% – 6% per sale
- Specific Categories: Rates vary depending on the product
- Exclusions: Some stuff pays zilch, so check before you hype it
Payment Terms and Cookie Duration
One of the coolest things? The program actually pays on time and keeps track of your referrals:
- Payment Frequency: Every 30 days, like clockwork
- Payment Methods: PayPal or check, your choice
- Minimum Payout: None! You get paid no matter how small your earnings
- Cookie Duration: 30-day tracking window—so if someone signs up within a month after clicking your link, you still get credit
