If you use electronic postage stamps, for example, a 1 oz coin can be placed into bubble wrapped sleeve for less than 2 oz. That would be a 68 cent stamp if printed through a service like Stamps.com or Endicia.

Then you USE A TRACKING LABEL 400 (which is completely FREE) and you put the tracking label 400 sticker above the delivery address.

This is the way to avoid the First Class Package shipping postage amount.
