    light-weight packages.
  • Pricing not affected by distance.
  • No fuel or home delivery surcharges.

Cons:

  • Maximum weight is only 13 oz.

  • No fuel or home delivery surcharges.

Cons:

  • More expensive than other lower cost USPS mail classes.
  • Less expensive options, such as First Class Mail, may be equally as fast.
