Although Walmart officials remain mum on the subject, several publications have reported that the world’s largest retailer is determined to regain its image as the low price grocery leader and lure back customers who are frequenting dollar stores and discount grocery chains.

The speculation is that Walmart is putting pressure on its food suppliers to keep wholesale prices down so they can pass along the savings to customers. And if any retailer has the power to convince wholesalers to absorb cost increases, it’s Walmart.
