I tried ordering prescription Royal Canin food through Petco.com and it was awful. No store anywhere near me carried this food and my dog has developed severe allergies so she actually has no food to eat that doesn't cause her harm until this arrives. Petco delayed and delayed. They lost the order, didn't send it to the vet for approval, couldn't manage to send the fax to the right place, wouldn't the prescription the vet gave me, and refused to take anything other than a *handwritten prescription* that specified a ton of detail. Even that they couldn't get together since they couldn't manage the right fax. After an hour on the phone with them and half a dozen calls to my vet I finally got them to call the vet for a verbal approval and they released ONE BAG of food. They didn't put the prescription into the system though. And after all those delays more than a week it still took five more days to get the food here. This is utterly ridiculous. Don't bother with this terrible company.
