The largest stash I found was around 24 also (a little more as it was two rows full at the time), but I didn't buy them all at once cause I was getting the rewards card punches. I ended up with four rewards cards by the end of my obsession. I have more quarts than I thought. I counted last night as I'm boxing it all up and I'm at 129 quarts. 120 stashed in Arizona, 8 at a friends house in Alabama, and one stragler I found in Utah during Thanksgiving that was left behind.
1st and only score :
(unless I can actually find more!)
