IMO two beers is generally not too much, but it sounds like a good way to trick me into paying the same price for 64 oz of beer instead of 72 oz.
It wouldn't work in the real world.
It's a marketing psychology thing.
Remember the Miller pony in an 8 pack? Sold like crazy. Folks don't consider the quantity (at least non-homebrewers
) ,just the count of the containers.
4 bottles < 6 bottles regardless or the total ounces.
