Where do you buy yours? I need to get some by the end of November so I'm looking for a cheaper place to get it.

Also, what brand do you use? I have been using Heartgard, purchased at my vet.

I just searched online and it was more expensive there than at my vet!

I know there have been threads on where to purchase flea/tick meds online. I'm wondering if I can purchase the heartworm meds there also.

THANKS!!
