It'd be interesting you did demand delivery pricing, so that pricing became more expensive at peak times (eg: 8AM) that way you can manage the effect of everyone wanting their drink at the same time.

You should start hyper local, one neighbourhood in San Francisco - SOMA? Hayes Valley? Mission? If you did it in a hyper local area you might just turn a profit at $1.50 delivery each.

I think this would also be hugely valuable to companies, such as being able to order all my teams starbucks drinks in one click.

I'm curious why coffee though? Most people do not appear to mind getting their coffee in the morning. Especially as it is so habitual. I hate laundry though! I hate taking my trash out. I hate not getting fresh bagels/fruit each morning.
