I love how in the last picture, she's selling you arrows while the other npc is showing you how to shoot an arrow (straigh at your face) ;

YES THIS IS EXACTLY WHAT I NEEDED THANK YOU FINE SIR!

It's compatible with every DLC, no problem with Hearthfire, but it's obviously not compatible with mods that alter the whiterun interiors. It's tested, I use it and it works fine, I cleaned it with TesEdit and it's fairly simple.
I don't know what "Villages overhauled" is, but if you are refearing to "Towns and Villages Enhanced", or some mod like this, yes, it alters the interior, also, "Skyrim Travellers" or other mods change merchants and my mod add arrows to some blacksmiths, so they could be not compatile. This is the problem.
Also, having 28 mods could create problems even if they are compatible sometimes, just for the loading order, there are tools that cheks that and optimize it.

I unsubscribed. I DL'd 28 mods yesterday and had to go through each one to figure out what was crashing my game. This was the mod that kept crashing my game. Most of my mods were just graphics enhancements that everyone uses. I know, installing 28 mods at the same time and having to spend time to figure out which one fucked my game up was kind of my fault.
Conflicts I could think of being possible - Skyrim Travellers, Villages overhauled (though I think this is just an exterior mod), maybe the dragon bone weapon one?
Maybe this mod doesn't work with Hearth?
IDK, it was kind of disappointing but after getting extra items for vendors mod I more or less have arrows covered by visiting blacksmiths now anyways.

I'll try it, mate. Elbon arrows too?
(I'm mostly marksman, I do like to sneak and shoot first...)
