The Disappearance of a Fan-Favorite
For years, Costco members could count on the familiar sight of the Kirkland Signature Organic Soy Beverage in bulk cartons. It was a budget-friendly staple for many shoppers, particularly those who were vegan, lactose-intolerant, or simply preferred a plant-based option. However, beginning in early 2025, customers began reporting the item's sudden and puzzling disappearance from store shelves across the country. The initial confusion gave way to frustration as members realized this was not a temporary stock issue, but a more permanent change. Online communities, like the r/Costco subreddit, became a hub for speculation and shared disappointment.
The Multiple Reasons Behind the Discontinuation
Several factors contributed to the removal of the private-label soy milk from the warehouse chain. While Costco itself rarely provides a single definitive reason for discontinuing a product, member reports and company-level analyses offer a comprehensive picture of the decision-making process.
Slow Sales and Shifting Trends
One of the most concrete explanations came directly from a Costco customer service representative, who cited 'slow sales' as the primary reason for the discontinuation. While the Kirkland soy milk had a dedicated following, its overall performance did not justify its shelf space compared to other plant-based beverages. This aligns with broader market trends. Sales of soy milk have been on a downward trajectory for years in the U.S., largely losing market share to the soaring popularity of almond and oat milks. Consumers have increasingly turned to these alternatives, attracted by different flavor profiles, textures, and perceived health benefits.
Supplier Negotiations and Contract Issues
Another frequently reported reason revolves around the relationship with the product's supplier. At least one Costco manager reportedly indicated that the company and its supplier were in a heated dispute over pricing. Costco is known for its meticulous contract negotiations aimed at securing the lowest possible price for its members. If an agreement cannot be reached, the company often opts to discontinue the product rather than compromise on its value proposition. One Costco customer service agent told a news outlet that the "suppliers and buyers could not agree on a price" for the product.
Costco's Inventory Management Strategy
The warehouse giant operates on a highly competitive and limited product strategy, constantly evaluating the market demand for every item in its stores.
Key considerations in Costco's product management:
- Performance Metrics: Products that underperform in sales are at risk of being culled to make room for more profitable, faster-moving items.
- Shelf Space Optimization: With limited floor space, every product must earn its spot. New, trending items often replace older, slower-selling ones to keep the inventory fresh and compelling for members.
- Supplier Relations: Disagreements with suppliers over cost or volume requirements can lead to a product's discontinuation.
- Product Evolution: Sometimes a product is removed to make way for an improved version or a different brand that meets changing consumer needs.
A Comparison of Plant-Based Milk Options
To put the soy milk discontinuation in context, it's helpful to compare it with the other non-dairy milks that have gained favor with consumers and at Costco.
| Feature | Soy Milk | Almond Milk | Oat Milk |
|---|---|---|---|
| Protein Content | High; comparable to cow's milk | Low; significantly less than soy or dairy | Moderate; higher than almond milk |
| Flavor Profile | Nutty, slightly beany; versatile for cooking | Milder, nutty; some brands are thin | Naturally creamy, slightly sweet; excellent for coffee |
| Texture | Smooth and creamy; excellent frothing | Thin, watery consistency | Very creamy and rich |
| Market Trend | Decreasing in popularity in the U.S. | Steady and strong market share | Fastest-growing in the market |
| Availability at Costco | Branded replacement now available | Multiple Kirkland and other brands | Multiple brands, including Kirkland |
The Replacement and What's Next
For those who were mourning the loss of the Kirkland brand, there is some good news. According to correspondence received by upset customers, Costco stated plans to bring in a branded soy milk replacement. The new product, often from brands like Your Good Foods or Silk, would rotate through the store's inventory. This is a standard practice for the retailer, ensuring members always have access to a variety of products while still managing stock efficiently.
As of recent reports, a branded, organic, unsweetened soy beverage from 'Your Good Foods' was indeed stocked in many warehouses, directly addressing the previous gap in the lineup. For members who frequent Costco Business Centers, other options like bulk Silk brand soy milk have also appeared on shelves. This indicates that while the Kirkland version is likely gone for good, Costco acknowledges the demand for soy milk and is adapting its offerings to meet it.

Conclusion
The discontinuation of Kirkland Signature soy milk was a disappointing moment for many loyal customers. It was the result of a combination of factors, including declining sales in a market increasingly dominated by alternatives like oat and almond milk, and challenges in supplier negotiations. However, the story does not end there. Costco has since listened to its members' feedback and introduced branded replacements, ensuring that a budget-friendly soy milk option remains available. This situation highlights the evolving nature of the plant-based market and Costco's pragmatic, sales-driven approach to its product inventory.
