Watermelons in Labrador, specifically. Only $55.41 per!.
Hard to believe that a house in Detroit can cost less than a watermelon, but capitalism doesn't care what you think, only what your wallet is willing to spit out.
Note that that is the government-subsidized price to help preserve heritage traditions or somesuch. There is of course no "right to cheap watermelons" or anything of the sort, especially living in the Arctic Circle, no more than there is a "right to ice palaces" while living in Vancouver.
That being said, providing subsidized food might reduce future health care costs, but the numbers are obviously unknown. Either way, this example shows why cities are the way of the future - economies of scale are pretty awesome.
