One example is the entry zone at the front of the store - you'd think that's a prime location for signage, deals, brochures, etc. But when you're headed through the door into the store you see almost nothing and stop for almost nothing, and then (in America) you tend to drift to the right and then you're 'in' the store. If you put a store directory just inside the door, nobody uses it. Move it back a bit so you can find it once you're into the store and suddenly it's heavily utilized. He has hard observational data for all these, so they're compelling in addition to being fascinating.
In August 2007, Amazon announced AmazonFresh, a grocery service offering perishable and nonperishable foods. Customers could have orders delivered to their homes at dawn or during a specified daytime window. Delivery was initially restricted to residents of Mercer Island, Washington, and was later expanded to several ZIP codes in Seattle proper. AmazonFresh also operated pick-up locations in the suburbs of Bellevue and Kirkland from summer 2007 through early 2008.
