Unlimited arrows of any type
To get unlimited arrows of any type, simply find someone that is doing target practise. Sneak up behind them and reverse Pickpocket just one arrow of the type you want, then Pickpocket off them any other arrows that they have. They will shoot an infinite amount of the arrow that you Pickpocketed on them, which you can pick up for free whenever you want - and it's not a crime!
Just make sure you save before you do this, just in case you get caught Pickpocketing.
