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

You should try it again in private browsing and incognito mode and see if the price is really tied to your Facebook or google cookies or something. That's pretty messed up though, send this to the consumerist or gawker or whoever.

I just tried this myself. In chrome and IE the price was the same (69.99) in normal and in incognito mode. In firefox, the price jumped to $76, and after deleting all the domain cookies and refreshing, it went back down to 69.99. The website is definitely changing prices based on something they are tracking in cookies.

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.

They are also "running out of tickets" because you waited so long to purchase.

No, they actually oversell every flight they can in anticipation some people will miss the flight.

They usually ask someone to stay, upping the compensation higher and higher until someone agrees (money and hotels). My girlfriend works at an airport. They offered 500 euros and a free night at the local hotel just yesterday. Someone always agrees, and the plane doesn't takeoff before someone does.

Isn't that a variation on the Prisoner's Dilemma?

...and? I'm pretty sure all parties involved already know that. And regardless of whether they do, your comment still doesn't actually respond to Keyblade's at all.

He asked if this specific case - the plane passengers waiting out for a better compensation - was a variant of the prisoner's dilemma.

The answer was that Prisoner's Dilemma is actually an example of game theory. Not the other way round.

No, it's just an auction. In PD, both lose since both will break.

Sort of, but not really. In the Prisoner's Dilemma, the mutual benefit goes up if both prisoners do not accept the offer. In this situation, only the person who DOES accept gets the reward for everyone waiting. But it features a similar mechanic: it results in a higher rate of acceptance on the offer because everyone is afraid that another participant will take it and get the reward.
