I never would’ve thought about getting the CCC there. I already feel like such a pig when I order from there, but I guess why not go full glutton? 
Never heard of them but will certainly try based on your rec. I wonder if they put them in some sort of insulating bag to keep them warm??? Also interesting about the mix of milk vs. dark. ATK had a test taste (specifically of choc chips), and Julia’s fav was bittersweet, which she thought tasted more “traditional” than the semi-sweet (I hadn’t realized until watching that semi- and bittersweet were diff). So that combo of milk + dark in the cookie is intriguing…
