Usually on horseback. Sometimes a stork will deliver it.
Yes
It gets delivered into your letterbox like your regular post. It gets to the recipient faster than regular mail. I use the service all the time because the items you mail can be traced like first class parcels of up to a certain size and weight. If you sign up for USPS Delivery Digest you will know that it's coming and when and if sent to others you can follow the progress at usps tracking online. I hope this helps.
