You can order Plan B from Amazon or one of the other online retailers. Typically will be cheaper but will also give a woman less time to waffle about taking it.

Saved my ass a couple of nights ago since now she's texting me about regretting taking Plan B cause she feels we could have been great parents. Fucking weird but I'm glad I had it on hand before she convinced herself not to take it.
