Mine Safety Disclosures is one of the most slept on blogs! Everything they write is a banger!

Can I get this in newsletter format or something?

I'm not familiar with this idiomatic use of "sleep on", can you explain it a bit?

Is it like "discounted" (not as in lower price, but as in to hold a low opinion of)?

It's modern slang for "underrated".[0]

This was way too engaging. Has there ever been a more recent follow-up with updated numbers?

I imagine it would be the same situation. I am not sure what the purpose of this presentation was anyway, Costco was never in any danger from Amazon. They are in two completely different markets.

The cost of energy and labor to deliver big, heavy goods to an individual's house is obviously more than the cost for individuals to go to a giant store and get it themselves.

If Amazon had opened a store like Costco selling bulk goods, then it might have made sense.

Costco stock dropped 10% when AMZN bought Whole Foods: https://money.com/amazon-whole-foods-costco-wal-mart/

Costco's profit was $2.7B when this was written. It was $6B over the last year.

The most surprising thing about that was how big an online retailer Apple is. I never quite realized that their standardized phones and computers mean I have never bought one in a store, not in the last 20 years …

If Costco had an Apple computer in the configuration I wanted, I would buy it from Costco because Costco offers 2 year warranties on computers, whereas buying from Apple would only get you 1 year.
