On the closest major corner to my house, there is a freestanding Starbucks in the parking lot of an Albertson's that has a Starbucks inside the store. I know of two other locations within 8 miles that have the same setup. That's six Starbucks outlets in three locations in an 8 mile radius. That doesn't include the four or five others that I know of in the same area. And, I don't even drink coffee so I am not looking for them.

I'd say they have a little overpenetration of the market...
