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 sell it for smaller amount? Or does anyone know of a brand i.e. smaller number expensive, so I could ask my gyno to adjustment it? I know Planned Parenthood solely charges $15.00, but they hold an intake allowance of approaching $50.00-90.00, even if you aren't due for a papsmear, so I don't reckon they would be worth it.

I'm pretty sure Microgynon 30 is the cheapest, which is why the doctors prescribe this pill first (free contraception within UK) above other brands of the pill.
