http://www.amazon.com/Durvet-Ivermectin-Pour-On-250ML/dp/B000HHOEIU is the link to a smaller portion through Amazon. It still isn't cheap, but at least it isn't a huge container.

Oh, this isn't at all what I was thinking you all were talking about. So it's not the Ivermectin paste I feed my horses. Hmmm... Okay, well, this looks like a liquid. Do you drop it down their beak.. or do you drop it onto their skin???? I think I'll buy some of this! But I'll look at Atwoods and see if they have it. I'd rather just have a lot of it on hand instead of a tiny bottle. You know me... I'm the pharmacy over here. I like to be prepared! LOL
