Hello! Thank you for checking out our on-line store. This store is run by a third party that carries many products that we don't carry in the clinic allowing us to give you more choices. However, they have pricing limitations in place that are beyond our control. We wanted you to be aware that the products that we do carry in the clinic will have a better price per dose due to manufacturer rebates and free doses that we can only offer in the clinic. If you have any questions or concerns, please feel free to contact us.
