Does that include half arrows or what?

For some reason I save some arrows from a good kill. But most of my arrows come from changes that I make in my equipment such as different bows, in which for some reason I can't figure out in a lifetime of shooting.

The aluminuim arrowsmakegood hot dog and marshmello skewers when camping with kids so I justify it as buying new skewers on a regular basis.
