Nope. Have never used them. I'm not opposed to the idea... Every time we've needed Vet Meds, they are as a result of having a sick dog, so we took her to the Vet. S/He prescribed meds and it seems kind of tacky to say "Oh, we can get the meds you're prescribing cheaper on the net" ("Plus we're willing to let the dog suffer for a few more days while we wait for them to come")

I guess we could get stuff like heartworm pills from the web site, when we get a refill...
