I can pick up a six pack, 12 pack or even a case of beer with one
hand
and carry it to the register easier than I can 3 loose 22 oz.
"bombers"-
so where's the "efficiency" in that?

"Use a shopping cart?" You know, when I'm forced to buy single
bottles
(12 oz, 16 oz, 500 ml., 750 ml or 22-24 oz.) I find myself ALWAYS
buying
less total beer than if I just bought a six pack and those "loose"
bottles just tip over and roll around, knocking against each other in
the bottom of "not designed for glass bottles" chromed-metal shopping
carts.

i don't know where you're buying your beer, but here in Western PA
where the Penn Brewery is, you can't buy single bottles, or as you
say, 3 loose 22 oz. bombers to put into a shopping cart to tip over
and roll around. So, as long as it's a packaged case, why do you care
how many ounces are in the bottle, the can, or in the aluminum
bottle??? Augustiner is available in a 18 aluminum bottles of 16
ounces per. And the aluminum bottle is a work of art!!!
