I signed up for the Pet Care program and with this saved money on my overall year of purchasing Trifexis. This company so far is the least expensive but, with high quality control of trifexis that I have found so far! Why pay extra if you don't have too! Andrew was my sales rep and explained all the numbers to me as it seemed too good to be true but, in the end he was correct! Thanks PetCareRX for the savings!
