There's a counter just inside the door with a guy sitting behind it, waiting for your question. If that's not wonderful enough, there are staff people all over the place; but not only that--they all know where you'll find what you came for, even if they don't work in that section. How refreshing is that!
The prices are good, the staff is friendly, they're centrally located; and you can get in, buy what you need, and drive away in less than 8 minutes. At Home Depot, it takes that long just to walk through the parking lot!
