Determining the value of a cup of coffee is relatively straightforward. When defined as a ratio of quality over cost, the value equation in this setting is easy to solve. How good are the coffee beans? What about the coffee maker? How fresh is the coffee? Finally, to determine the cost, simply look at the sign in the coffee shop or the price on the package. The best value comes from high-quality coffee offered at a low cost.
