I purchased a six month supply of frontline plus for dogs weighing 45-88 lbs and was sooo happy to have found frontline at such a good price. The website says that they send genuine frontline products i didnt know that people counterfeited these things until i went online today. My dogs are still itching and not getting any better with their infestation. Now im out 52.00 and i would try to send it back but i used some of it so i am sure that they arent going to give me my money back. Just letting people know that i thought that website was legit as it uses paypal to pay and has all this stuff that really makes you believe but when you get down to it they are selling COUNTERFEIT PRODUCTS!!! DONT USE THEM AND HARM YOUR ANIMALS
