These photos show how Walmart is crushing Target in one crucial way

Target's grocery business is about 15% the size of Walmart's, according to Moody's analysts.

That's largely because shoppers fail to see Target as a destination for food, according to Neil Saunders, CEO of the consulting firm Conlumino.

"In essence, we believe Target needs to rip up the grocery rule book and reinvent its rather bland store environment," Saunders wrote in a recent note to clients.

Some analysts think there's no hope for Target in the food business, however, and have suggested that the retailer cut its losses by quitting selling groceries altogether.
