I have come across a ministry called Bezeugen Tract Club that gives away free gospel tracts. After you enroll in the club (for free) you will receive a 30 day supply of tracts once a month. I just got my first shipment today.
Bezeugen is a German word meaning, "To bear witness to; affirm as a fact or truth; attest"
Here is the link to their homepage where you can check out their great website and all the cool evangelism ideas they have.
