Vista Print has been around a long time, and you probably know them as the company that prints 100 business cards for free. They're not the BEST quality prints, or the fastest with shipping, but there is something to be said about offering free products.
They currently offer 100 free postcards (full color front, B/W back) if you're willing to pay a minimum of $5.45 for shipping (which is quoted at 21 days lead time). It works out to about 5 cents per card.

Put a big, bold Ron Paul message on it. Use some catchy facts about him, some of which are available from his "about me" page on RonPaul2008.com. Some you might consider:
- He has never voted to raise taxes.
- He has never voted to raise congressional pay.
- He has never voted to increase the power of the executive branch.
- He voted against the Patriot Act.
- He voted against regulating the Internet.
- He voted against the Iraq war.
- He does not participate in the lucrative congressional pension program.
What you do with the cards is up to you, but be sure to get them out of your hands as fast as you can.
Note: If you're willing to spend a little bit, the best deal I've found on larger quantities of postcards is GotPrint.com. You can get 5000 postcards for $129, which works out to 2.5 cents a piece. The print quality is very good.
