Diamondback Drugs is a great resource, and I feel fortunate they are right here in Phoenix. My dog has required several compounded prescriptions and others that are off the shelf. The prices are fair and competitive, and they have been quick to get them to me either for pickup or delivery when I needed them. They are also super friendly and even throw a treat in the bag for my dog (and spoil her with treats when we need to pick up the Rx). They also have a nice (but small) waiting area with kids movies on a flat screen tv in their lobby area.
