Something Funny About Walmart Price Rollback

Walmart usually has the lowest prices on groceries, and their "rollback" promotion where they cut prices a few cents to save you even more money must be successful since they've kept it around for so long. It would appear, however, that Wally World is no longer content with just rolling back prices a few pennies. I noticed this very dramatic price rollback on Coke products in the store today. Yes, five dollars is much better than fourteen dollars for a 24-pack of Coke. Problem is, I can't remember ever having seen multipacks of soft drinks priced at nearly sixty cents per can. Seems like someone's fudging the numbers here.
