kariva $46.79 without insurance (generic for mircette...which is about 55), most generics run about $30/month, some are a bit more. Brand name drugs tend to cost more, but most states will automatically require the pharmacy gives you the less expensive generic. Seasonale can run up to $160/pack (1 pack = 3 months)

Let me add: Planned parenthood charges based on a sliding scale...depending on your income. If your girlfriend is a college student, most college health clinics give out birth control at drastically reduced prices! (It was only $8/pack for brand name mircette at my previous college!)
