Kroger is taking drastic measures to slash prices — and Walmart should be terrified

Kroger is slashing prices and going on a hiring spree. 
The grocery store chain recently cut the cost of 1,000 popular items in 120 of its stores, retail consultant David Merrefield writes on industry website The Robin Report. It's also in the process of hiring 14,000 people at its 2,800 stores to boost customer service. 
Kroger has annual sales of $115 billion, about half of Walmart's US sales. Still, the retail giant is starting to pay attention.
