Beware.. If they only have half of a 30 day prescription in stock, and need to order the remainder, you better not wait until the first (partial) 15 day supply is used to then go and pickup the rest..
When the the second half of the RX comes in (within a day or two in this case), you'll get a generic recorded message to notify you, but no one will tell you that it's then sent back if not picked up within a week (as opposed to up to 30 days like CVS, or even just 15 days, when the partial that they previously filled would be just about used up)..
They'll then tell you that you need to re-order that same remaining 15 days at your full co-pay. Super shady stuff.
