Compared to Amazon, MMC has a very small number of SKUs, inventory that never goes stale, and prices that are only affordable in the context of B2B transactions. It’s not a comparable service.
I did think it was pretty funny that the same tweezers CVS sells for $7 a piece in midtown Manhattan costs 5/$1 on Aliexpress. Only difference is the CVS tweezers are available immediately whereas I had to wait 20 days to receive the ones from Aliexpress - though I more or less have a lifetime supply now. :)
But B2B is weird. If I need my employer to ship me something that I’ll use next month, I am hard pressed to get them to ship slower than 2nd day air.
Maybe you didn't see the Footnote:

[1] "Jeff Bezos is an infamous micro-manager. He micro-manages every single pixel of Amazon's retail site. He hired Larry Tesler, Apple's Chief Scientist and probably the very most famous and respected human-computer interaction expert in the entire world, and then ignored every goddamn thing Larry said for three years until Larry finally -- wisely -- left the company. Larry would do these big usability studies and demonstrate beyond any shred of doubt that nobody can understand that frigging website, but Bezos just couldn't let go of those pixels, all those millions of semantics-packed pixels on the landing page. They were like millions of his own precious children. So they're all still there, and Larry is not." https://gist.github.com/chitchcock/1281611
I buy screws there all the time. It isn't like it is $10 a screw! It's like a nickel or less.
