As a former employee of a veterinary hospital, I am familiar with the Royal Canin line of dog and cat foods. Royal Canin seldom offers coupons, unfortunately. If your veterinarian has recommended a specific blend, that can only be purchased through a licensed veterinarian, please ask your vet if he/she is aware if Royal Canin currently has any rebates available for that specific blend. If he/she has recommended a blend that can be purchased at a local pet store, your best option is to "shop around" and see which store carries the product for the best price. Often, these pet store chains offer rewards cards, just like a grocery store, which can lead to further savings.
