Consider yourself warned: Do not order from Roadrunner Pharmacy because, in my experience, they are incapable of filling a simple order in a timely way.
A little background: They quoted a very good price for my cat's meds so I gave them a credit card number and all the other required info and placed an order. The order didn't arrive on the day they said it would so I called them. I will spare you all the details regarding the number of phone calls we exchanged and how much time I invested trying to find out what happened to my order. Suffice it to say that more than a week has elapsed since I placed my order and now my cat is a day away from running out of medication, all because Roadrunner Pharmacy was so inept. Yes, you might save money using them, but you will need a boat-load of patience if you attempt to place an order and it disappears into the ether, as mine seems to have. This company is not worth the aggravation. I'm taking my business elsewhere.
