I was running out of this product. So, I decided to search it on the internet and VetDepot.com came up, with a good price, a few dollars cheaper. So, I ordered it. I had a delay because I needed the approval of my dog's vet. So, I called the vet and told them that VetDepot just needed to fax the order to them for approval. They did it! So, from now on, I know how to order products from this website.
