Overall, a very positive experience. The company had the lowest price for the flea treatment our cats needed. After we placed our order, the company promptly called us to discuss any questions we had about our order. When we placed a second item, which was backordered, they sent us the treatment right away, and then sent the second package in a separate shipment with no additional shipping charges. Customer service was efficient and helpful whenever we called with questions or concerns. We are new customers but will gladly continue to use this online pet pharmacy.
