Poster: What You Pay Depends on where You Pay

In this poster, we present an initial investigation of price differentiation between apps, mobile sites and desktop sites. We developed a tool to extract price information from different outlets simultaneously, with self-made scrapers using Appium and actual smartphones to collect data from mobile platforms. We use our tool to gather data from six travel companies over a period of four weeks for a small number of f lights. This allows us to contrast each company’s offers on desktop, mobile app and mobile browser platforms. We find several differences between various outlets, such as price differences between mobile and website price, or price difference between French and German website. As such, we find that a more thorough, structural investigation is warranted.
