I have been using Allivet for some time. I started when the prescriptions were getting too expensive with my vet. I have been very happy with not only the price but how fast they get the order sent. The only problem I have had was with my vet not responding to their fax. But Allivet, when called, sent another fax and got it done. Whenever I call, the salesperson is so gracious and helps with whatever needs to be done. I will continue using them and would recommend them to anyone.
