The United States Postal Service is offering a great deal for those wanting to target their neighborhood, a carrier route, an entire zipcode, a city, county or more for only 17.7 cents per mailing piece. What is the catch? Your piece has to be a “flat” size, meaning, wider than 11.5 inches OR taller than 6.125 inches OR more than 0.25 inches thick. So, you get all that extra real estate in which to promote your business or event, for a fraction of the postage cost of a normal letter.


  • 17.7 cent postage rate (retail)
  • Greater than 11.5 inches wide but less than 15 inches wide
  • OR Greater than 6.125 inches tall but less than 12 inches tall
  • OR Greater than 0.25 inches thick, but less than 0.75 inches thick

If any of these three requirements are met, the piece qualifies as a “flat” according to the USPS. We have multiple size flats available, just ask us about it.
