So I ordered my pet's arthritis medication through Petco.com because the price is half the price of the vet HOWEVER with my pets first refill not only was I charged TWICE but I was told that they had to confirm the prescription with the vet. I argued because even the bottle showed 3 refills. Why would they need another order from the vet?! Even the vet called me asking why this company was requesting a refill when they gave refills on the original prescription. I was told that even though there were refills they still needed to verify the refills with the vet. This to me means that refills don't mean a thing to Petco. As far as the double charge, Petco said they only charged me once so I had to dispute the second charge for the prescription. Now here it is 2 months later and I saw that Petco is refilling my pets anti-inflammatory medication without the headache of requesting a refill from the vet. As I mentioned they already approved refills. Anyway, again I am double charged for 1 prescription. Apparently they charge when they begin the refill process and AGAIN when they mail the medication. This time Petco took down my information so hopefully I won't need to dispute through PayPal but honestly I don't have much faith. I'm definitely going to keep track and get my money back. This whole process has wasted so much of my time I had to review it with the world. Personally I'd rather pay more than work with Petco prescriptions in the future. I can't wait until I'm out of refills! Buyer beware!
