Unfortunately, I frequently stop here. If they do not have the required number of pills to fill the prescription, they will let you know as soon as the shipment arrives and I go back and pick-up the remainder. The drive-thru is highly undesirable because it is not a window so you cannot see the person to whom you are speaking, but rather it is a pneumatic set up like at the bank. If you are picking up, you have to send it back, wait for them to send you the form you have to sign that you have picked up your prescription and also payment. Wait for them to then send your receipt and your prescription. Honestly, after all that it is really faster and easier to just park and go in and pick the thing up. Heaven forbid you have a question for the pharmacist. However, they are open 24 hours. Trust me, if there is a car at the gizmo(where it should be the pharmacy window) just park and go in.
