Speedy health was fast
Speedy health was fast, safe and efficient. I didn't have to drive 35 miles into town to wait at the doctor's office for 2 hours to have them write me prescription. Then wait another 2 hours to have the prescription filled. It came right to my mailbox. I highly recommended speedy health.
