I picked up a new size bottle (at least for me) of Ice Mountain Spring Water at Sam's Club. It's a 20oz bottle that is a touch shorter than the 16.9oz bottle. I picked up 2 cases of 28ct for $5.50 each.

These were vend packs. Is this a new size that will make it to to grocery stores. Will the 20oz btl replace the 16.9 btls? It would be cool if it did. Any one know about this?
