I never saw it for $4 and I checked often because tractor supply quit selling the duravet aplle flavor one we had been getti g there , though i was buying during 2021. There were folks selling it for over $50,a tube at one point, but it was stil. Available from tractor supply back then and other places as well at that point. I ended up buying the liquid from Jeffers innthe south east I beleive. I had a few tries getting it from Amazon but I waited and waited on 2 places who didn’t bother informing me thay they were out. I finally had to contact them to see what was up.
Anyways, it’s good stuff to have on hand as it also works for the flu. I was sick around 5 times or so during the whole pandemic time, and each time I used ivermectin, and got over whatever it was within 2-3 days (thoug I was left pretty weak for 2 of them for several days after)
Just checked my order history, $22.30 for a 6-pack of Durvet apple flavored in mid-November 2020. So $3.72/ea. I remember the singles being $4, or $3.99 or so.
And I’m convinced they use the same fake apple flavor the Jolly Rancher people use in their hard candies. It sure tastes the same.
