So what is losteverything talking about? How do they charge people different prices if the prices are printed right there on paper?

Not this specifically, but with a totally electronic system and no point of sale to anchor there is large opportunity to easily and programatically have dynamic pricing at the known individual level. Supply, time of day, whatever can be instantly baked into a pricing system.

And why not? No humans needed to change pricing. Plus i would think you could scan to get "your" price. Prime member $x. Etc..

I hope i did not imply this was happening now..

Aaaah... you said

> I wish there was a mention that 5 people can buy the same milk and all can each pay a different price (and none know what the other paid either)

And the answer why it isn't mentioned in the article is... because it's not a thing that's happening.

Yep. The author gives reasons for Amazon's decisions. I wanted a pricing discussion. My bad

It's hard to do that in a physical store since everyone can see the same price display. I doubt many people would be happy in a store where they need to look up every single price on their mobile device.

Kohl's seems to be doing pretty well with that system. They print a high price on the tags, then discount it by rack, and mail out 30% off coupons with short expiration dates to some of their rewards card holders every month.
