I pay less than 25 cents per mailing for postcards with printing and postage.
I have them printed through gotprint.com and I have a local guy that charges me $60 per 1000 to address the cards and use his bulk mailing permit. The mailing permit is what gets you the presort standard postage rate. Your postage will be determined by how tight your mailing routes are. I mailed to like 3 or 4 zips this year and my avaerage postage was like 19 cents.fertnsquirt.... Who do you use?
