Amazon sells the same brand (Kirkland = Perrigo Pharmaceuticals in WI) for $15 as well.
Yes I have taken Zyrtec daily for the last 15+ years. Started with actual Zyrtec, then switched to generic Allertec from Costo about 6 years ago and then switched to generic GoodSense about a year ago: https://smile.amazon.com/GoodSense-Allergy-Cetirizine-Tablets-Count/dp/B00G9E1GYA/ref=sr_1_8?keywords=zyrtec&qid=1557496795&s=gateway&sr=8-8&th=1
I have not tried wiping cat down with a damp washcloth. Is this something I should do daily?
Amazon sells the same brand as Costco for $15 for a years supply without the need for a membership. You can buy it here. If you have Amazon Prime, you can get it shipped overnight for free.
