I dont look at fletching as a way to save money. I look at it as a way to customize MY arrows, and to tinker with different setups to get the optimum flight from MY arrows. Your local shop most likely wont do that.

I found fletching to be very easy. My setup consisted of a $30 jig and clamp, a $3 tube of fletch tite, a dozen arrow shafts, and a 100 pack of vanes.

Look towords fletching your own arrows if you want to make your arrow unique, and you want the convenience of being able to fix arrows when you need them. Keep using the shop if you want to save money. Because you WILL strip off perfectly good vanes trying something new. At least if you're any bit of a tinkerer like I am.
