How would you fell if prices on amazon were higher for you than for others because of your income, residence or historical purchase data? With all the margins going to amazon instead of the sellers.

Amazon did try and user feedback was enough back in the day to make them stop - it wasn't the dominant retailer back then and users had much more power, so there's that.

Byw plenty other retailers already do or did adjust prices: Apple users are commonly targeted for being price insensitive.

I'm pretty sure Amazon already does this - prices are different based on your location and purchase history at the very least. Sometimes its obvious but other times they will just push a different seller to the top of the list which effectively changes the price. You can chalk it up to their 'dynamic pricing' but it always seems to favor me over my wife (the majority of our purchases go through my account).

This happens all the time, but it depends on user ignorance or apathy.

Just shop using different browsers or devices. Use incognito modes for everything. Use multiple entry points. Use multiple loyalty cards (and don't intermix credit cards amongst them.

For a real-world example, I use 4 different Starbucks cards. Each gets very different reward offers, every time. Y

I don't disagree. If you have done this much research though, you could actually set up a little case study on this, write an eBook with nothing more than screenshots on how the price changes, and put it up for sale as something which will save people atleast $x per month. :-)
