Okay, just looked up their gross profit margin and Costco is consistently operating below 14% and up until May of this year, was below 13% more than they were above. I thought I'd heard it was even smaller than that, but that doesn't appear to be the case.
The fact that they do sell memberships is why they can go with the smaller margins, yes, and it puts some downward pressure on the cost of items they sell, too, since there's all kinds that would love to be sold by Costco but can't because they can't afford to cut into their own profit margins.
Hey, you're the man when it comes to opinions and research. You've provided great reasons for why they might do it, too. It's almost like you've been sitting in on some meetings or something.
That's really sad, though, if/when they do it. Using a blockchain to basically ensure their total control and monitoring of your every move. I'm going to have to leave planet earth because there won't be anywhere else to escape from them in the world.
