Um, I buy both with and without a plan. My stash is pretty small right now, and I'm trying not to spend too much on non-essentials at present, but in the normal run of things if I love it and I have the finances I'll get it. I figure that as long as I'm not buying fabric for the sake of it, or stuff I don't like (e.g. because it's cheap) then it'll work out in the end.
