My $1000 vasectomy was completely covered by my insurance except for a $45 copay.  I rarely need prescriptions ,except for my 11 month old son and my fee for prescriptions is usually around $5.  I don't see what is wrong with having birth control pills covered in the same way.  

I really don't have any sympathy for businesses who don't "want to cover birth control," like any other prescription medication.  If you can't run your business according the rules of a free and secular society, then you shouldn't be running a business.
