For your first arrows go to a pro shop and buy a half-dozen, they'll fix you up with the right length, spine, etc. Then you can order online if you find a real good price. Personally, I try to go to my local pro shop for arrows because the online prices are only a little less, and I like giving the guy my business. I'd hate for him to go out of business! That's just the way I feel (I wouldn't be caught dead in Wal-Mart either!).
