We live in a very rural part of western Florida. We are so far outside of town we have to drive 5 miles to get a cell phone signal. All of our items are sent out USPS (Continental United States ONLY). A recent problem was created when a buyer used a mail forwarding company to get a book they purchased sent to Columbia, S.A. Needless to say it did not arrive in three days. As a result our former payment processor (PayPal) refunded the money.
So our policy is this: we send everything out to the Continental United States via US Mail, Book Rate. If you need/want a book faster it can be send that way only YOU will have to pay for the shipping for the items.
