I've been in plenty of home improvement stores over the years and can probably count the number of college kids I've seen there on one hand. It just doesn't seem like someplace a college student needs to shop unless they need to build a science project of some sort, and I can't think of any time I ever visited a hardware store back in my college days.
Now an auto parts store on the other hand - I would think they would see much more traffic from kids looking to maintain their rides as cheaply as possible, but even there, most kids would probably opt for beer over changing their oil.
