McGuckin's is not your father's hardware store. This store has it all, and it's a misnomer to refer to it merely as a hardware store.
Sure, they have hardware, but they also happen to carry everything else, too. It's too much to list it all here, but it's safe to say that if you were looking for pretty much anything, and you didn't want to leave Boulder, I could send you to McGuckin's and you'd find it.
Also, they staff the place with armies of helpful, blue and green vested individuals. You can't swing a dead branch in McGuckin's without hitting a smiling customer service representative.
Only downside: more pricey than Dad's hardware store.
