This is sort of a fascinating chart. We knew that inkjet ink was expensive, but who realized it was that expensive? Of course, ink makers would argue that the cost is for the technology, and the cartridge (which holds the ink) itself. But damn, dudes, you guys came up with those little-bitty plastic cases with the complicated chips in them in order to make more money. No excuse!
This is interesting, but the relevance is elusive. I remember when gasoline was shooting over $4.50 gal., some stupid politician (R-Naturally) arguing that gasoline was still cheaper than milk. Like anyone needs 16 gallons of milk at a time. But geez, ink costing almost twice as much as human blood? Wow.
