If it wasn't already obvious that Target is nervous about Amazon, it is now. Target has acquired another same-day delivery startup, Shipt, for a cool $550 million. The deal should speed up Target's plans to offer same-day delivery in its stores. It's expecting to have the feature available in half its stores by early 2018, and in the "majority" of stores in time for 2018 holiday shopping. Your options will largely be limited to groceries, electronics, "essentials" and home products, but Target plans to offer products from all its major categories by the end of 2019.
