Postmates isn't just for late-night take-out delivery anymore. The service just launched grocery delivery in Los Angeles, Manhattan and San Francisco. It's called Fresh. More than that, the firm completely overhauled its app to make ordering a 12-pack of Dr. Pepper or a loaf of bread (or basically anything else you forgot while at the grocery store) a lot easier. A post on Medium claims that it shouldn't take more than a half an hour for your goods to arrive -- supposedly a quarter of the time some of its competitors. It's about the same wait time for a Postmates booze drop-off. Amazon Fresh, on the other hand can take hours to make a delivery.
