Query: Nothing wrong with Frontline, of course.

These folks are selling a 3-month supply at 6-month prices.Nothing illegal. And there's nothing wrong with the product itself.The item listing (Frontline Plus Flea and Tick Drops for Dogs & Puppies Up to 22lbs) doesn't mention how many pills are available; in the description of the item, it does say, toward the bottom, that you are getting 3 pills. Just over $18 each, and that's before tax and shipping.You get 3 pills, not 6. If you are aware of that, go on and buy!
