https://www.theverge.com/2017/11/8/16621474/postmates-fresh-on-demand-grocery-delivery-amazon-instacart >Postmates today announced the official launch of a new grocery delivery service, called Postmates Fresh, that puts the company in more direct competition with Amazon and Instacart. Postmates, one of the longest running on-demand and logistics starups, has allowed its users to order items from grocery stores in the past. However, this new product, which will exist under a new grocery tab in its iOS and Android apps, is Postmates’ first official foray into grocery store partnerships. The company is also revealing a full app redesign today to mark the launch. >Postmates Fresh is starting in San Francisco, Los Angeles, and New York City, and it’s partnering with local organic farms and grocery stores to provide everything from meat, vegetables, and dairy to alcohol, deserts, and home supplies. Postmates is putting delivery times at 30 minutes on average, compared with two to three-hour reserved windows for Instacart and Amazon Fresh.
