I will have to disagree to some extent. I just got done doing a saturation mailing of my menus with my own permit. Because a majority of my residence live in rural routes, I just had to address them to “Residential Customer + Anytown + zip +Rural Route #” I only had to pay 13.9 cents per piece. I figured I just paid for my permit on this first mailing.The amount you would save is not worth the hassle. With the changes in the compliance requirements for cleaning your list etc, you are much better off to work with a printer who has a permit and will perform the required steps. Yes, they will charge you a small fee, but if they are geting your printing business it should be small ($100-$150) Takie the time you save and use it in some other way to build you business or control costs. You will come out way ahead.
