Costco Affiliate Program 2026: Does It Exist And How To Earn

Quick answer: Costco does not run a public affiliate program that pays on products bought at Costco.com. The only Costco affiliate offer is a membership-only program on a couple of networks. It pays a small flat fee per new membership, listed on FlexOffers at $3.20 to $6.40, with a 1-day cookie. If you want to earn from Costco content, you will mostly be using alternatives and Costco-adjacent programs.
Costco content is hugely popular. Haul videos, Kirkland Signature reviews and “what’s new at Costco this month” posts pull steady traffic. Many people assume there must be a Costco affiliate program behind all that content. For product sales, there isn’t one.
This guide explains what actually exists in 2026, what it pays, and the legitimate ways to monetize Costco-related content. If you are choosing a niche from scratch, our list of the highest paying affiliate programs is a better place to start.
Does Costco Have An Affiliate Program?
Not in the way most people mean. Costco keeps prices low by spending little on marketing, and it does not pay publishers a commission on the groceries, electronics or household goods its members buy. Costco does not publish an affiliate page on its own site, and it does not show up as a product advertiser on the major retail networks.
What does exist is a narrow program for new memberships. A Costco Membership offer has been listed on affiliate networks for several years. According to the network tracker Affilitizer, it was on CJ from May 2024 until it was removed in November 2025, then appeared on FlexOffers in March 2026 and on Partnerize in April 2026. It pays only when a referred visitor buys a new membership, not on anything they buy afterwards.
Many older blog posts describe this as “the Costco affiliate program” and quote the CJ terms of $3 per Gold Star and $6 per Executive membership. Those terms belong to the CJ listing that has since been removed, so treat them as history.

How Costco Membership Commissions Work
The membership program pays a fixed amount per sign-up rather than a percentage. A Gold Star membership costs $65 a year and an Executive membership costs $130, following Costco’s 2024 fee increase. The listed payout is the same flat fee whether your visitor later spends $200 or $20,000 at Costco.
A few details shape how much you can realistically earn:
New members only. Renewals, upgrades of existing accounts and reactivations of recently lapsed memberships typically do not qualify.
Very short tracking. With a 1-day cookie, the visitor needs to join almost straight away. Many people prefer to sign up in the warehouse, which you cannot track.
Returns apply. Costco refunds membership fees on request, and refunded memberships are generally reversed.
Terms change between networks. Check the live terms in your network dashboard, not in old reviews.
How Much Can You Make Promoting Costco?
From the membership program alone, not much. Here is a sizing example using the FlexOffers listing. If your content drove 100 tracked new memberships in a month, you would earn between $320 and $640, depending on how many chose Executive. Getting 100 online sign-ups inside a 1-day window takes a lot of traffic, since most readers of Costco content are already members.
Compare that with a percentage-based retail program. The same audience sending $20,000 a month in sales through a program paying 4% would earn $800, and that income grows with basket size. This is why most successful Costco-focused publishers earn from display ads, sponsorships and other retailers’ affiliate programs rather than from Costco itself.
Costco Vs Sam’s Club Vs BJ’s For Affiliates
If your audience loves warehouse clubs, the two other big US clubs are more affiliate friendly than Costco, because their listings pay on product sales as well as memberships. Network listings change often, so confirm the live terms before you build content around them.
Costco: memberships only, listed at $3.20 to $6.40 per sign-up, 1-day cookie.
Sam’s Club: listed on FlexOffers as 4% of sales and up to 16% on memberships, with a 3-day cookie.
BJ’s Wholesale Club: listed on FlexOffers as 0.8% of online sales, with a cookie of up to 30 days.
Legitimate Ways To Earn From Costco Content
Since Costco will not pay you for product sales, these are the realistic options:
Instacart. Costco offers same-day delivery through Instacart, and Instacart runs an affiliate program on Impact. Content about getting Costco delivered can link there.
The same brands elsewhere. Many brands sold at Costco are also sold at Amazon, Walmart and Target. Reviews can link to those retailers’ affiliate programs.
Display ads. Costco deal roundups, monthly coupon book previews and price trackers draw repeat traffic that suits ad networks.
Sponsored content. Brands that sell through Costco sometimes pay creators to feature their products. This is a direct deal with the brand, not with Costco.
Membership guides. Pair the membership program with useful content such as Gold Star vs Executive comparisons, and with practical guides like how to cancel a Costco membership.
One option that is gone: Costco Next, the members-only marketplace that sent shoppers to partner brands’ storefronts at a discount, closed at the end of August 2026. It was never an affiliate program, but older articles still mention it.
Who Should Join The Costco Membership Program?
Personal finance and budgeting sites that compare warehouse club memberships
Moving and new-homeowner guides where readers are setting up household shopping
Deal sites and newsletters that cover new-member promotions
Large-family, meal-prep and bulk-buying blogs
Small business sites that explain the Business membership
If most of your readers are already Costco members, the program will pay very little. Focus on the alternatives instead.
How To Join The Costco Membership Affiliate Program
Pick a network that carries the offer. In 2026 it is listed on FlexOffers and Partnerize.
Create a publisher account. Add your site, traffic sources and payment details.
Apply to the Costco Membership program. On FlexOffers you can find it through the Costco Membership listing.
Check the live terms after approval. Confirm the payout per membership type, cookie length and any restrictions on search ads or coupons.
Place links on membership-focused pages. Put them where readers are deciding whether to join, not on product reviews.
Tips To Earn More From Costco Content
Target non-members. “Is a Costco membership worth it” and Gold Star vs Executive content reaches people who have not joined yet.
Watch for new-member promotions. Costco periodically offers a Costco Shop Card with a new membership. Readers who see that offer are more likely to join online.
Explain the Executive math. The 2% annual reward, capped at $1,250, only pays for itself at higher spending levels. Clear break-even math builds trust and sign-ups.
Monetize product content elsewhere. Link Costco-favorite brands to retailers that pay a percentage of sales.
Build a deals list. Weekly Costco deal emails grow an audience you can monetize with sponsors and other programs.
Cover seasonal moments. Holiday, back-to-school and summer outdoor buying spikes drive search for Costco content.
Sam’s Club: the closest warehouse club alternative, with listings that pay on sales and memberships.
BJ’s Wholesale Club: a regional East Coast club with a long listed cookie.
Amazon Associates: the widest catalog for linking to brands Costco shoppers already like.
Frequently Asked Questions
Does Costco have an affiliate program in 2026?
Not for products. The only Costco affiliate offer pays a flat fee on new memberships, and it is listed on FlexOffers and Partnerize rather than on Costco’s own site.
How much does Costco pay affiliates?
FlexOffers lists $3.20 to $6.40 per new membership, depending on type. Nothing is paid on what members buy.
Is the Costco affiliate program on CJ?
It used to be. Affilitizer records the CJ listing as removed in November 2025, so guides that send you to CJ are out of date.
Can I earn commission on Kirkland Signature products?
Not through Costco. Kirkland Signature is Costco’s own brand, and Costco does not pay commission on product sales.
Does Costco have a referral program for members?
Costco does not run a standing member-get-member referral reward. It does run occasional new-member promotions, often with a Costco Shop Card.
What is the best alternative to a Costco affiliate program?
For warehouse club content, Sam’s Club. For general household and grocery content, Walmart, Target and Amazon pay on product sales and fit most Costco audiences.
Conclusion
Costco is great content but a poor affiliate partner. There is no program for product sales, and the membership-only offer pays a few dollars per sign-up with a 1-day cookie. Use it on pages aimed at people deciding whether to join, and monetize the rest of your Costco content through retailers that pay on sales.
