In fact, as it turns out, the cost of printer ink oustrips the cost of many other popular liquids, including bottled water, Red Bull, vodka, penicillin, human blood, and crude oil. Gizmodo
shows off a graph created by reader Shaun, in which he compares the prices of these and other liquids. HP Black Ink #45 tops the list, with a price of $0.71/ml, while human blood runs a distant second, at $0.40/ml. Crude oil comes in dead last, just beating out bottled water.
That’s right: it’s back to writing things down on paper for me.
