You search using their tool instead of going to Google, Yahoo or other places, and they donate money to Pro-Life Charities.
Advertising with them is also very cheap in contrast to other services.
Pro-Life bloggers and web-developers reading this blog should draw attention to this, and place a link to the tool in their sidebar near the top. I'm going to do this next time I edit my own template.
You can get to the HGPI-Michigan blog anytime from this blog by clicking on the Our Lady of Guadalupe in the sidebar!
