Has anyone successfully ordered prescription meds for their pets online?

We have been going to a new vet and he won't refill a monthly script for our cats
prednisolone without seeing her. This is costly and excessive, not to mention difficult physically for me and my 15 yr old cat.

She has been on this med seasonally for years, she has asthma. Our former vet gave us a 3-6 month script. He sold his practice to a kid who looks to be about 14 yrs old who seems much more interested in how much he can make rather than caring well for our cat, and me.
I explained I had health issues and cannot come monthly.

Anyway, if anyone has ordered online, would you let me know which company you used? Thanks so much,
Diandra
