Well currently I'm paying $70 a month (I switched to this because there was a generic but now the pharmacy is saying there isn't one yet I know people on it???) so I figured it has to save some sort of money.

But I was curious if I could just start using it at any time? I obviously already dropped off the prescription and got it filled which is how I found out it's still costing me $70. Do I just go present the card at the time of payment and it will supposedly help me save? Or should I have turned it in when I dropped of the prescription.
