Grocery Wars

With AmazonFresh trucks now a regular sight around the city, Google Shopping Express running a huge ad campaign for its Costco and Whole Foods deliveries, and Good Eggs constantly adding vendors, grocery delivery is white-hot in SF right now. The latest salvo: Instacart has secured the rights to deliver for Rainbow Grocery beginning today, which, as we learned last year, is definitely the crowd favorite among chefs for their personal shopping. Though we're sure not every member of the crunchy co-op will be thrilled about their new techie bent. [EaterWire]
