I assume we're all talking about prices for the 750ml size (which I can usually get on sale every few months for about $19.99).

I noticed the liter size showing up in my favorite store lately, but I didn't note the price. With that rectangular bottle, it sure looks a lot bigger in the full liter than the 750ml. More noticeable than the difference between the 750 and liter sized regular bottles like Wild Turkey.
