re: Coca-Cola

In many stores, the vendors stock the soft drink aisle and set out the special displays. It's possible that the vendor doesn't change the shelf tags since that is a sore function. Even though the shelf tag said $3.99, maybe that was for the old 8 pack. Did the 6 pack ring up as $3.99 or $2.99 as Coca-Cola suggested it should? Had the 8 pack to 6 pack conversion just happened?
