Broad-head Arrows
To get free broad-head arrows, go to the tavern in the Stone Market Plaza where there should be 3 guards, one with a bow, upstairs. Dispose of the guard downstairs. After you do that run down and jump behind the bar, the guards upstairs may come after you but they can't get behind the bar. The one with the bow can shoot at you, so crouch down behind the bar and wait for him to ready his arrow, then stand up for a sec and crouch back down, he will fire his arrow into the bar and you can claim it. Repeat this to get full broad head arrows.
