Kroger turned their pharmacy over to CVS a year or two ago. Kroger has been experimenting with Kroger Marketplace "superstores" (there is one in my town) so there is some real potential in them joining forces.
Kroger is huge. Even if you don't have a Kroger branded store near you, you have a Kroger owned store near you. Ralph's, Fry's, Smith's, Dillon's, Harris Teeter, and a dozen or so others. Not to mention Fred Meyer Jewelers (there is one in the Kroger Marketplace in my town. Yeah, you can buy milk and diamonds in my local Kroger store.
Kroger is the largest supermarket chain, and the second largest retailer, behind Walmart. Target is the second largest discount store chain behind Walmart. The two combined would be a formidable competitor to Walmart.
This could get interesting.
