Find the number of pounds or kg of coffee that Keurig buys and sells each year. Divide that into Keurig's total revenues to find out what price to weight ratio (including the cost of the machines and coffee) their customers pay. As they sell to resellers, add another 50 percent or more for subsequent markups, and you will get an idea of what Keurig costs in comparison to just buying a can of coffee off your grocer's shelves and brewing it yourself (add a little for the cost of a new electric coffee pot each year to the non-Keurig cost, it costs around a month's Keurig's coffee for 1 or 2 persons). I have not been through this calculation for a few years, but the result I got suggests that coffee drinkers have been paying a large penalty for their preferences already, equivalent to a tax rate that would be very unlikely to survive if imposed by any non-totalitarian regime.
