Have you tried Omaha Vaccine (www.omahavaccine.com) or K-V Vet (www.kvvet.com)? These are two sources that I use frequently as they generally have good prices, and K-V Vet doesn't charge shipping on most items. --- Robyn Allwright --- ziffanyrobyn@earthlink.net --- Ziffany Great Pyrenees & Tibetan Mastiffs
