Sticker Shock

I thought gas prices would be jarring, but it's dog food that's the real kicker. At home a typical 44 pound bag of dog food cost around $30. Here, I just bought Grady's first bag of food (we shipped some over), and 33 pounds cost about $70--basically triple the price per pound for comparable food (and it's just Eukanuba, not some special Swiss brand). I'm outraged. Aren't there some sort of free trade agreements (PFTA?) governing pet food?
