I don't know how prices translate, but where I live in the US you usually get corn in the husk for $1 each. I prefer it in the husk because cooking with it on makes it taste better.
Here in Iowa we only buy corn in season. Picked the same day, on the husk for $6/dozen. I won't even touch the packaged stuff you sometimes see off season, and given how rarely I see if I don't think many others will either. In season the farmer delivers half her corn to the grocery store and sells the other half from the back of her (happens to be a girl where I live, other places it was a man) truck on the side of the road.
