Has anyone heard of Believersoutpost.net 

They are a Christian only donation site, that donates a portion of your shopping proceeds to a Christian charity of your choice, even your own local church, all you have to do is request they be added to the list.  They donate to your choice of charity by searches only too.  They even post the percentage of your donation.  I really like this site because I know that I'm not donating funds to a company or search engine that might also be donating to other groups I don't necessarily agree with.  They are a Christian based donation service only.  There isn't a lot of bells and whistles to the web site, but some people like this, it's very clean and simple to use, they have good stores too.  I'm wondering how long they've been around, because I just came across this, but it looks goods.
