While Frontline, Frontline Plus, and Advantage do not require a prescription, when you buy them from anywhere besides a veterinarian, there is no guarantee (from the manufacturer) that you will be purchasing the genuine product, as these companies sell only to veterinarians.

Where can I buy FRONTLINE Brand Products?
FRONTLINE Brand Products for dogs and cats are available from your family veterinarian.
Why are FRONTLINE Brand Products only available through my veterinarian?
It is Merial's sales policy to sell our small animal products only where a veterinarian/client/patient relationship exists. Merial believes that the veterinarian is the only professional qualified to serve the health care needs of pets, the concerns of their owners and the appropriate use of our small animal products such as FRONTLINE Brand Products. |

I am not trying to be argumentative. I am just warning people that when you buy these products elsewhere than a veterinarian clinic, you take a risk.
And check with your vet about prices, you may be surprised. The vet clinic I use deliberately undersells on line pet supply stores for these products (they check prices daily) because their clients pets' safety comes first. Plus, when you buy the genuine product through your vet, if you buy a six pack, you get another tube free.
And never EVER buy flea products or other pet meds on places like e bay.
