[Costco] Kirkland Infant non-GMO formula milk $20.99

I was in the Costco business centre at Warden and Eglinton (Toronto) earlier and came across this deal. I am not sure whether this deal is available in other Costco branches. Regular price is $26.99. From what I recall, it goes on sale two or three times a year.

I used to purchase them for my kid but don't need it now. Maybe other parents will find it helpful. Happy hunting!
