Just wanted to second getting it already bad from the pharmacy. It has happened to me, at least once. Yep, it was a pretty "High volume" big-chain kind of place, I assume it was left out in the sun or on the heater or something. The 3 penfills I used over 5 days all seemed to work at about 1/3 effectiveness, before I went and bought a new batch from somewhere else, that immediately worked as expected.
