As a long-time Costco member and very minor shareholder (like 10 shares), lawsuits like this are frustrating. It is in my best interest as both member and shareholder for Costco to relentlessly look for opportunities to reduce costs, including getting credits back from procurement and sourcing. It would be costly to try and determine the tariff impact to every member and then pass it back along. I'd rather see those funds contribute to keeping prices low by offsetting other cost pressures.
