They finally have them regularly on the shelf here. Sometimes I find them in the 'health food' section or organic section (not sure why).
I did buy a case from Amazon at one point and it was like $2/box. That was in the winter when I didn't worry too much about a package sitting out.
That being said, they are my 'emergency food' in my car. I opened one up the other day, heat of summer, and it was just fine after being in the car for 2 months. Chocolate bits a bit melty, but it was still crispy.
These are also my substitute breakfast at work if I'm in a rush leaving home.
GLAD YOU LIKE THEM!
