Whatever happened to the dozen?

Safeway Flyer - October 26, 2012

Until pretty recently, cans of soft drinks have been sold in multiples of six. The six-pack, dozen and for the truly thirsty, the 24 pack.

But now Coca-Cola is offering a "Big 20 Pack". The interesting thing is that the "20 pack" is almost the same size as the old "24 pack". Will this new package confuse some some consumers? How will they compare prices?

And the ironic thing is that the "Big 20 Pack" is actually a smaller pack. Oh well, most consumers won't even notice.
