$10.49 for Durvet apple flavored at the TSC near me, I just looked. It was $4 in Nov of 2020, FWIW.
Back in the early days of Covid there was a post here where someone compared the paste Ivermectins at TSC with a nice graphic presentation of good/better/best and I’ve tried in vain to find it but failed. I’d the Durvet one the middle of the road or the bottom?
