Costco has historically carried grass-fed ghee from several brands, including Tin Star Foods and Ancient Origins. While it's not clear which brand the poster was referring to, they may be talking about Tin Star Foods ghee, since it's still on Costco's website. However, it appears to be unavailable for shipping in most areas. Tin Star Foods ghee has disappeared from Costco's shelves before. In 2021, the brand issued a recall due to a quality issue that affected the product's shelf life. It's unclear if quality control issues led Costco to discontinue the brand, but it seems that the clarified butter may be missed.
