Matt Yglesias points to this story about putting a Costco store in an urban location, in this case downtown Vancouver, and the benefits of such a thing.
The new store is a feat of engineering and an unusual mix of uses. It is built in a hole bordered by GM Place, the Georgia viaduct and the escarpment on the eastern end of Vancouver's downtown. The 127,000-square-foot store, built by Concord Pacific, has two floors of parking below it, two floors of parking above it, and then, above that, another four towers of residential condos with 900 units. [...] To appeal to what is expected to be a slightly higher proportion of downtown shoppers, the store stocks a bigger variety of home-ready meals -- chicken parmigiana, prawns and pasta, souvlaki, lasagna, and the like -- electronics and leather goods, said Ross.
