Online shopping: Price wars
In late June this year, travel website Orbitz disclosed to the Wall Street Journal that it utilises price customisation software, stating that it believes Mac users will pay US$30 to $40 more per night for a hotel than those using PCs. On average this was found to be an 11 per cent increase, with some customers on Macs spending up to 30 per cent more than their PC-using counterparts.
Price customisation software isn't just at work with laptop and desktop computers; it is also detecting mobile devices. In a study by Forrester Research and Shog.org, nearly 50 per cent of surveyed online retailers said users of tablet computers placed bigger orders than those using regular computers. Therefore, if you're shopping online with not only a tablet, but an Apple iPad, you meet the double-whammy criteria and have the highest chance of being charged top prices.
