It depends, I sometimes get a pre-made dough from the bakery if in a hurry and I can't find the right ingredients, I think that is cheating but it has happened more than once. I have used boxes if we are traveling, or for the ease of it with kids or making many different types.
But I do prefer to make everything from scratch , it just isn't a practical solution all the time.
I am very happy that there are alternatives in boxes , it also makes it easy to get started when most of the thinking and planning is done and you only have to add a few ingredients like water, milk or butter.
