Don't forget that the post office also supplies a variety of envelopes and boxes for priority and express mail shipping...at NO CHARGE.

Many times I've received packages that were shipped first-class or parcel post, opened the box and found "free" stuff from the post office used for packing. (A flat-rate box that was wrapped in a brown paper bag and shipped for a lower rate; glasses wrapped in priority tyvec (sp?) envelopes, placed in a post office box, then in a larger plain box; priority boxes cut into flat pieces of cardboard, then placed in a bubble envelope to protect paper goods...etc.)

I believe they even advertise that they will deliver these shipping materials to you...at no charge!? Below is a very small sample of what they offer. Many of the items have a maximum order of 400-600 pieces!
