Not a new story (although this video was uploaded in Jan 2014).
From this 2012 story:
Microsoft has demonstrated an early prototype of a Kinect-powered shopping cart, which is being developed for Whole Foods by Texas-based company Chaotic Moon. The project is called the “Smarter Cart” and it uses a tablet and scanners to read the items you place inside, check whether they’re on your shopping list, cross them off and ring them up. The motorized cart can follow you around the store and has voice recognition and speech so you can give it instructions and it can let you know if the item you added wasn’t on your list or is the wrong type of item.
