Where is the cheapest place to get Frontline Plus with discount for buying alot?

I actually buy the six pack of frontline plus for the xl dogs...u can order it for about $73 on KVvet.com
What i do is dump all 6 vials into a container..i then put .5 cc per 15 lb body weight for each of my animals. i have 3 cats and they get a drop. it's more cost effective and works well. that way, u don't have to buy the frontline for the dogs and for the cats. u can get it all at once. my mom, myself have been doing this for about 4 years and i've gotten several of my friends to do it as well and there have never been any issues.

i found a website that sold it cheaper than in the stores. i think it was advantage.com but im not sure. try that. it came with 3 in each box so that might work for you.

I cheat. I use Advantage. I buy the red size which goes up to 55 lbs. My dogs are about 40 lbs, so I use most of it on them and save a few drops for the cats. Advantage is the same product for both cats and dogs, it just comes in pre measured doses. Iv'e never had any fleas since I've been doing that.

I use global flea control out of british columbia. I believe I listed their service under flea control. I got 8 months of Advantage for medium size dogs for an awesome price. They are on ebay under flea products.
