Low-cost birth control pills?

I'm paying $31.99 out of pocket for Levora birth-control pills at Walgreens. Does anyone use this brand and know somewhere that sells it for less? Or does anyone know of a brand that is less expensive, so I could ask my gyno to change it? I know Planned Parenthood only charges $15.00, but they have an intake fee of like $50.00-90.00, even if you aren't due for a papsmear, so I don't think they would be worth it.Low-cost birth control pills?
I'm pretty sure Microgynon 30 is the cheapest, which is why the doctors prescribe this pill first (free contraception in UK) above other brands of the pill.
