Think grocery store in a bus, and you'd be imagining FreshMoves.org. It's a mobile fresh produce market, that comes to the neighborhoods without fresh food option. Unlike other mobile stores like Starbucks Train or Burberry Gifts or Meat Subway, Fresh Moves isn't a matter of luxury and convenience.It's about necessity and education of consumers who have been raised on fast food and haven't had a green produce as an option before. Most of these customers don't have access to fresh food, mostly because grocery stores are too far to get to without a car (which most of these people don't have) and carrying tons of groceries on the bus or two isn't exactly the activity of choice for most people. Fresh Moves aims to overcome this obstacle by making greens easily accessible even to the most impoverished and cut-off neighborhoods. Its targets are community centers, schools and other busy locations. Kudos.
My guess is that Google, once it figured out that it hasn't exactly figured out demands of the retail market (remember Google boutiques?) decided to get into retail delivery. It's a great way to be first in the same-day delivery market and to create both customer- and retailer-lock in via its monumental data services. Once switching costs become too high, Google can monopolize the demand and expand its delivery market. It's not a bad idea, even if at the first sight it seems as an unlikely one for the Google brand.
