I m sure most people know about the insanity of printer ink s price. However, this wouldn t be a real list of overpriced technology without highlighting it. Printer cartridges are much like razor blades. Most manufacturers will take a loss on the printer itself, counting on making their money back on selling ink cartridges. Since refilling or using non name brand cartridges can be really bothersome, they can charge almost anything they want for the cartage. Which tends to be an arm and a leg.
