How do I ship something at the post office?

Do you need a special envelope like the type you get at the post office to ship something overnight?

• I want to just put it in a regular bubble wrap envelope but do I need one of those envelopes that you can only get at the post office?

• Answer:

  You don't need the express mail packaging, but you do need the express mail form. Also use the sticky labels that say "Express Mail" and put them on the front and back of the envelope.
