Stores are a marriage of a logistics business and a marketing business. The split is about 75%/25%. That marketing component is ripe for disruption that directly connects the original sellers (brand, manufacturers, authors) to their end users (consumers, readers).

The winners will figure out how to separate the logistics of local availability from mobile/local marketing.
