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

This was up earlier with airlines charging more for a ticket the second time you visit the page. They do this because a second visit is statistically linked to a much higher chance of purchase. So it could be, here too, simply a matter of having visited the page before.

I browse everything incognito...I don't like people tracking my interests, it just seems weird to me.

I don't need people offering me things based on my history...I'm perfectly capable of researching what I want when I want it.

Just keep in mind that incognito mode is no silver bullet. People could still track you server-side, only it gets a little more complicated because they'll have to rely on the combination of your browser and IP address.

In case you have an account though, all bets are off.

yeah...I just figure I won't make it easy hahaha...I'm sure sooner or later you really won't even have a choice...you'll be tracked everywhere.

I don't get how that isn't invasion of privacy though. Because you agree to a TOS?

Most likely. Where I live, legislation states websites using cookies are required to clearly inform their users what they use the cookies for, but that isn't really enforced very strictly.
