I have so far bought at McCormick and Pratt, Ridge and Pratt, and Broadway by Devon-ish. They had a lot on Sheridan (5500) but the cat didn't print!
I did not clear any shelves at any store-left at least as much as I took.
I was in Glenview yesterday and called the store on Lake Ave and Patriot Blvd and they had about 15 boxes-but my kids were tired and it was dinnertime so I didn't stop-and I figure 48 boxes is pretty darn good!
Hope this helps.
