I just got back into achery middle of last yr, but most of that stuff I've bought off line. I shop around locally and then online, choosing the best deal. It's always online though, most web sites offer free shipping or the price is low enough to supplement shipping cost.

Paul of P&A Archery Supplies is a great guy. He has good prices. Paul has donated a lot of supplies to TBG fund raisers, not to mention lots of his own time to help folks out with their equipment.
big jims in albany ga has anything you will ever need and fast shipping when orders are placed, plus if you have any questions why ask the kid behind the counter when you can talk to the man or the lady who actually build and sell custom bows and arrows for a living. an extra dollar is well spent to support local professionals who are always willing to help.
