Many thanks to the reader who tipped me off on this! I was so excited to hear that Freshkote is now available OTC, online. For the first time in a coupla years now, one of Dr. Holly's wonderful drops is available again 'over-the-counter. It's not cheap, but it's good :-) (I do not have any financial interest, direct, or indirect, in this product, for the enquiring minds that want to know.)
I see Amazon has it for $34.84 or $65.92 for a twopack.
