On average, SuperTargets take up the most square footage at 177,291 apiece. Expanded food stores come in at 129,281 per. General merchandise stores run 119,084 square feet each. And CityTargets are not too far behind thus far at 102,800 square feet per location. Once inside you really cannot tell the difference between the stores, with SuperTarget the obvious exception.I probably shouldn't expect a run-of-the-mill retailer like Target to do anything but mail it in. It knows it can drive revenue in places like San Francisco. So, at least from today's perspective, it sees no reason to break ground on anything but smaller stores. That's disappointing.
