Zombi U is $29.97 and Nintendo Land is $39.97 at Costco in Kitchener. Should be the same across the Ontario, Quebec, and the Atlantic provinces.
Wait, are those download codes that Costco is selling? Or do you present that at the register or something in exchange for your game? I've never been to Costco so I haven't seen a setup like this before. Either way, I had been planning on picking up Zombi U from the eShop during the Ubisoft sale but this is even more tempting.
