Inkonomics.

 
Think a $5 gal­lon of gas is crazy? Dri­vers in Nor­way are cur­rently pay­ing $9 a gal­lon, and Ger­mans pay just over $8.

That’s cheap com­pared with gold, which right now is at $1,700 per ounce.

Think gold is expen­sive? Con­sider this: If cars ran on print­ers’ ink instead of gaso­line, each trip to the gas sta­tion would cost $100,000. Accord­ing to PetaPixel, to fill an Olympic-sized swim­ming pool with ink would cost bil­lions of dollars.

My tiny office printer uses HP21 black ink car­tridges. The best deal (often on Ama­zon) goes for $12. Each car­tridge is 1.4 ounces.  Now, if you can remem­ber your high school con­ver­sions, 1 US gal = 128 US oz. That means at $12 per car­tridge, a gal­lon of the cheap­est ink in our office costs about $1,536 per gal­lon, and the cheap­est color car­tridge is about $3,364 per gal­lon. Yikes!

What about my fancy photo printer? A long time ago I learned a valu­able les­son: the cheaper the printer, the more expen­sive the inks. I have also learned that over time, the mar­ket lead­ers tend to be more sta­ble in their pric­ing of con­sum­ables, because they are bet­ter equipped to react dur­ing rough eco­nomic times.

Keep this in mind dur­ing the hol­i­day sea­son when you see some “impos­si­bly good printer deals.”
