I would say on avg I buy about 3 dozen shafts or so a year and I have usually have about 10 dz or so on hand. Most years I am switching and shooting between about three bows. it pays to just have a variety so I can choose what I want to tune for a certain bow.
Certain shafts I will buy if I need them or not providing I am getting them at a great price, and I know I will use them in the future.
