Well, there is the fletcher shop in the Vivec Foreign waistworks, but it requires a mod. It's an official Bethesda mod, so you can find it on their site. It's a bit strange that there aren't any standard fletcher shops to begin with. In the shop in Vivec you can buy (or steal of course) all sorts of ammo for crossbows, shortbows and longbows, as well as throwing knives and shirukens and such. You'll also find the Daedric longbow inthere. I usually steal it, since it's a bit expensive, especially when you're still early in the game. I use area effect arrows, which have the effect of a grenade. So if you shoot at one cliffracer, and there happen to be a few others nearby, they'll get hit as well.
