I have a prescription for Cialis but it's horrifically expensive in the US and not covered by my insurance plan. I ordered generic Tadfill on line from here at less than 1/10 the US price; it arrived in NYC as promised in about two weeks. I paid for the tracked service. The envelope was a nondescript padded white envelope. Product is as advertised, ordered 30 pills and received 30 pills. Recommended, will use them again.
