Don't pay the initial fee and yearly fees for your own USPS mailing permit. When we process your mailing, use our permit for free instead!
Design your piece as a letter-size rather than a flat to save postage.
If you are mailing a postcard at first class rates, keep your size between 3.5" x 5" and 4.25" x 6 to get the cheaper postcard rate rather than the letter rate.
