There are a bunch of generic types of [levonorgestrel-based EC pills](https://www.bedsider.org/birth-control/emergency_contraception#costs_tab) for sale without a prescription over the counter or online. Generics are usually cheaper than brand names, and the cheapest alternative we know of, [AfterPill](http://afterpill.com/), is only $25 including shipping. Note that AfterPill _doesn't_ offer expedited shipping, so you have to order it in advance, _not_ after an emergency!
