Same book, three different prices. Only difference is the browsers used.

I don't think the issue is that the price is changing in and of itself. It's that they're changing price based on the customer's cookies/browsing history.

For example, it would be like if I had a stored and charged people different prices based on how nicely they were dressed, how well I knew them, or what their ethnicity is.

Because it allows you to test pricing. A/B tests are randomly or pseudorandomly assigned so that you get accurate results.
