A while ago, a nice pharmacy clerk informed me that the prescription drug I was taking was actually cheaper if I paid for it myself instead of paying my insurance plan’s copayment. I was thrilled at this news because that also meant I could get more than one month’s supply at a time (another insurance plan restriction, and one I’m sure the drugstores don’t mind since they can get customers in more often). In the past few years I’ve been through many insurance changes with companies changing plans or me changing companies. I have to remind the pharmacy people each time they put in my new insurance info to please check the cost of my prescriptions to make sure I can’t get them cheaper without insurance. I don’t know how many drugs are this cheap, but if you have suspicions, you may want to check it out. There are some other iterations of this where I’ve ended up paying less than my $10 or $15 copayment, but I’m confused as to how that works. It may vary with each insurance company or perhaps even the pharmacy?
