Jeremy makes a great point about shipping from large online retailers:

When I'm making the choice between UPS Ground and FedEx overnight, I'm shooting in the dark unless I know where it's shipping from. It if comes from Reno, I don't care. Give me the cheap rate. But if it's coming from across the country, I might want to spend the extra bucks.

Give us that info, and let us make an informed decision about which shipping option we want.
