We've probably discussed "come with" to death, so I think it's OK to allow some digression.

"Ya sure—you betcha" is a stereotypical expression supposedly used by Scandinavian old-timers. It is well known in Minnesota but mostly used facetiously and spoken in an appropriate accent. It is not yuppie-speak; more the exact opposite.

I have seen "Ya sure—ya betcha" printed on the label of Red Hook Ale, from Washington State, but I think they have changed their design recently and eliminated the slogan.

Another expression you sometimes hear in Minnesota is "Come here once." I don't know why they add "once"; it means exactly the same thing as "come here." It's usually spoken in the abrupt commanding tone that you might use with a child. If you're speaking to an adult and you want to be polite, you would say, "Would you come over here, please?" I haven't heard "I'll go to the store once" however.
