I realize that product choice matters, and if Sam’s has what you want and Costco doesn’t, that’s a good reason to stick with Sam’s.
However, does conscious capitalism matter in your choice? It does in mine.
I was a member of Sam’s for 16 years, primarily because there was no Costco nearly as close. During that time I learned that while the two companies’ business models are nearly identically, their philosophies are vastly different. Costco is known as a much more conscientious company. They pay employees about 70% more than Sams, and they offer more and better benefits.
There are too many articles on the internet about this to select one. So here’s a search link based on a comparison of Costco’s and Sam’s ethics. Enjoy the reading.
I’ve noticed discussions on this forum about how Costco seems to be supporting keto. My hypothesis is that the more conscientious company is going to evolve more rapidly toward health trends of their customers.
