That's true, we should be able to walk up to the counter and say
"Give me a 12 pack of Moonies, two cartons of cowboy killers, 200 rnds of that Honaday XTP .45, and oh yeah, throw in one of those Dan Wesson 1911s too while you're over there".
"What?, a two for one special on Remington 700's today? Cool!, my wife will kill me, but their on sale. Add them in too! See ya next week"
