A 'Grocery' Christmas Carol: The Ghost of Supermarkets Future explores the extraordinary transformation from American Supermarkets Past - including the meteoric rise over the past 20 years of national / discount grocers Walmart, Target, Costco, Amazon, Aldi, and Dollar General - to Supermarkets Present. It reviews the importance of scale, grocery M&A and regulatory attempts to curtail it, as well as the potential consequences of these dynamics in alternative versions of Supermarkets Future. All profits from "A 'Grocery' Christmas Carol" will be donated to Feeding America and Nourishing Neighbors.
