negative volume discount

My local Safeway supermarket has 12-packs of 16 oz. Snapple on sale (slightly) for $9.99, but it also has individual 16 oz. bottles “buy one get one free” for $1.39. I guess the message to take from this is that the cardboard carton on the 12-pack is somehow is worth $1.65.
update: My local Giant supermarket has 12-packs on sale for $5.99.
