Here is a detailed review on the Costco affiliate program.

If you’ve been following, you would have noticed that we’ve been writing more on affiliate programs lately. From Target to Walmart to Wayfair to Home depot to even Nike affiliate programs.

Gone were the days where you had to rely solely on the Amazon affiliate program to earn via affiliate marketing.

Relying on a single source of income is totally a bad idea! and without knowing the intent of the source is out-of-the-woods.

Take, For instance, if Amazon’s affiliate program closes tomorrow or even decides to drop down their rates to 1%, many people would contact HBP.

Costco statistics

According to Zippia, The company has over 105.5 million members with annual revenue of $166.76 billion.

All these began way back in 1993, as a result of the merging of two major pioneers of membership warehouses/clubs at the time – Price Club and Costco

The two companies had operated in close to similar strategies – Purchase goods in huge members from big brands and sell them to their members at cheap prices.

Obviously, this strategy paid off and today, Costco is ranked 6th in the top 50 global retailers, 10th in the topmost admired company, 8th in brand finance best retail brands, and many other achievements.

What Products Can You Promote in the Costco affiliate program?Illustration of a girl searching for affiliate products on Costco affiliate program

One of the red flags in most affiliate programs is the Lack of sellable products.

How do you even intend to make sales with poor products?!

Well, this is not the case for Costco, as you can promote all products available at

However, Costco, unlike other big retail companies, does not focus on selling everything; rather, they offer products that your audience will definitely want to buy.

Since Costco’s major customers are usually subscribed as members, a good percentage of their products are stocked based on members’ requests and best-selling items.

So, in other words, some of the types of products available in Costco are prone to fluctuate.

This complies with Costo’s statement in one of their post (tagline); “Not everything…just everything you want” and the popular “if Costco doesn’t have it, I don’t need it”.

In general, products available at Costco are just a complete package for any viable affiliate program.

Let’s take a look at some of their popular product categories.

  1. Home improvement
  2. Appliances
  3. Clothing & Luggage
  4. Home & kitchen
  5. Health & personal care
  6. Mattresses
  7. Gourmet foods
  8. Furniture
  9. Gift cards
  10. Health & personal care
  11. Sports & fitness
  12. Tires & Auto
  13. Jewelry & watches
  14. Patio & lawn

  16. Home Services (installations)
  17. Computer
  18. Electronics
  19. Groceries & pets
  20. Floral items
  21. Baby

A whole lot, right?

That’s pretty much better than the Target affiliate program and also a little bit low compared to the Amazon affiliate program.

However, since the majority of Costco products are from reputable and popular brands, Costco still has a stance over Amazon.

Recall, 59% of shoppers prefer to buy new products from the brands they trust.

So In turn, there are higher chances of conversion when promoting Costco products.

In all, Costco’s cheap prices are just points of attraction for buyers and since they’re well-known, buyers have no fear of being scammed.

This being said, let’s move over to the next section…

Costco has no stated policies/restrictions for its affiliates program – What do you expect from an affiliate program that has no landing page?!

However, it has one apparent restriction for affiliates and that’s a geolocation restriction.

Cookie Duration (Referral Period)Referral period and cookie duration of Costco affiliate program

Costco affiliate program, unlike several other affiliate programs, employs the use of a session-based cookie.

Heads Up – Session-based cookies are cookies that are stored while a user browses the web and would get deleted immediately the browser’s window is closed.

So this means that if a user clicks on your affiliate link and maybe decides to buy the product subsequently. At closing the window of the link, your affiliate cookies would be destroyed. Meaning that you’re no longer affiliated with the purchase of the product and you won’t earn any commission.

Other Policies

As said earlier, Costco has no stated policies for its affiliate program. However, to stay on the safer side, it’s ideal you follow the usual policies of an average affiliate program:

At the time of registration, your site must be Live and not under construction.

Before applying, your site should have a decent amount of content.

Legal, non-sexual, non-violent content should be avoided on your site.

Your website should be Family Friendly.

You shouldn’t promote any illegal material/product on your site

Commission Rate  illustration displaying Costco affiliate program commission rate

Sadly, this is where the bad side of the Costco affiliates program comes in.

Costco affiliates program does not work in percentages as many other affiliate programs would, rather, it employs a flat-rate payout structure.


According to Oxford Language, The flat rate structure is simply a pricing structure employed by marketers to charge a fixed fee for a service, regardless of usage.

So let’s bring this home…

The flat-rate payout structure means that affiliate marketers would be paid a certain amount of money regardless of the type and amount of product sold.

Costco affiliate program employs the flat rate payout pricing plan.

And as said earlier, Costco runs mainly based on membership purchases. Meaning, people subscribe monthly or manually to get products at discounted prices.


So, the company uses purchases made only by members (not normal customers) to pay affiliates. The higher the level of the member that purchases your product, the higher you earn.

Basically, the pay is $3 for all Gold Star membership purchases and $6 for all Executive membership purchases.

Regardless of the type and amount of product you sell, Costco’s commission per product still remains constant.

Imagine referring sales to a product that is worth $600, you still get to earn the same $3 – that’s bad!

Alternatives of Costco Affiliate ProgramCostco affiliate Program alternatives– Costco vs

1. Amazon Affiliate Program

Amazon affiliate program vs Costco affiliate program

The truth is that you can’t make mention of affiliate marketing without quoting Amazon, the pioneers of affiliate marketing.

Amazon has been on the system for quite some time now, and over the years, the company has drastically evolved. However, one major drawback of the program is its 24 hours cookie duration (referral period). Yet, this is pretty much better than Costco session-based cookies

Excluding the fact that the Amazon affiliate program is a popular and recommended one, the company itself is a leader in the e-commerce industry.

Amazon’s products are focused on a whole lot ranging from retail goods to digital content, from web services to e-books. This as well applies to their affiliate program.

2. Target Affiliate Program

Target affiliate program vs Costco affiliate program

Target Corporation is a well-known retail corporation based in the United States founded way back in 1902.

Target is the eighth largest retailer in the United States and the retailer corporation worldwide after Walmart, Amazon, Costco Schwarz, and 8 others.

Coming to their affiliate program, Target’s affiliate program is one of the worthy opponents of Amazon as well as Costco. Target commission rate ranges from 1% to 8%, however, it comes in an increasing proportionality. Thus, the more you sell, the more you earn.

In terms of referral periods (cookie duration), the Target affiliate program comes in handy; a 7 days referral period (cookie duration) is pretty much better than Costco session based cookies.

Here’s a detailed review of Target’s Affiliate Program

Final Thoughts

Sincerely, the Costco affiliate program is not really a good deal, however, with high traffic, good marketing strategy you can earn yourself a few tens, hundreds or probably, thousands of dollars (You can equally do this with any other relatable affiliate program!)

On the other hand, their so-called Session-based cookies, flat commission rate, membership blah blah blah, is just hell!
