A gift for a crossbow hunter

A hunting buddy and the owner of the land I hunt on is having a birthday just after gun season starts. He just got a Barnett 350 ghost cross bow. I would like to get him something for it but I don't know jack about crossbows.

I'm thinking he could always use bolts or broad heads. Brand and or type needed.
Or anything else cool for a crossbow?

Suggestions! 1,2,3 go!!!!!!

Id do broadheads if ti was me.

Academy gift card!!!

The gift card idea is my personal favorite.... been trying to get my wife to give me gift cards instead of other stuff for a long time...
