I have never used mail order yet but I would not hesitate to use it if I had to.
The reason? DH and myself have three maintenance meds that we take, the doctor always gives us prescriptions for 3 months at a time with refills of three months at a time. My co-pay is still $25 for each for a 3 month supply, however I have heard a lot of people say they pay $25 per month even on mail order, in other words , it would cost me $75 for a three month supply for one medication. If I had to mail in for my maintenance meds, I would not have a problem. I use the local pharmacies for the short term meds.
What ticked me off the other day while I was waiting for my dd's meds, was that out of 6 customers I saw helped while I was waiting, only one of them had a $5 copay, the other five customers all used their access cards and had 0 co-pay, then here I come, I get my bill....$25 co-pay for me, and I should consider myself lucky because it could be worse !
