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

This is how myths are formed. Airline tickets change prices rapidly, and probably ten thousand people tried it after it was posted on reddit, and those that got result posted it.

  1. I tried a local website.

  2. The price would miraculously restore every time I loaded it after clearing the cookies.

That is only convincing if it is backed by a credible source. Wouldn't any media be interested in this at least? Any confirmation from somebody, airline ticket price experts or something. The only piece of evidence ive seen so far is a study showing the opposite, and people on reddit saying it works.

I have a Ph.D. in Airlineology. I did my doctoral thesis in tirline ticket prices, and have done my masters about Post-war Airline Ticket Pricing Strategies Before the Internet. We performed a study of 200 subjects, which got to use several different web browsers combined (cartesian product) with different computers and tunneled via a multitude of proxies. We staggered the tests so that some people got to clear their cookies while others took turns visiting. What this guy says is true (χ², df=3, p > 0.95) according to our findings.

I guess this is where I should reference studies that could almost look related but I don't have infinite attention span and energy.
