It's a great idea, in theory. But who's the target market? Wealthy professionals have a wife to bring them stuff or have personal assistants (hard to believe in the world of dual income households, but I have friends that do just this). Young, less wealthy professionals just go pick up the items themselves or have friends pick them up for them. College kids aren't going to pay for such a service, they enjoy taking a break from studying to go pick up something. And yes, I know, I'm sure there are stay at home husbands that do errands for their wealthy professional wives, I just don't know of any.
