Id like a mod that a merchant you go to and tell what you want(3x glass ingot,etc) and they will charge you an amount more than what its worth and then you have to wait so long and then you pick it up...this would solve the reloading and reloading to get the items you need from merchants...i dont know how hard this would be to do(hopefully) not very hard but probarly would be complex but it sure would be cool.

You want a merchant that just does that? There is http://www.nexusmods.com/skyrim/mods/42726/? however, it is only for weapons/armor. You pay an inflated amount, and wait x number of days and get your goods.

Expanding it to include just crafting supplies ought to be simple, if you use the construction kit and look under the hood.

edit: Not used that mod myself in ages, but it worked well back then. I used to use it to get armors various mods added in.

I need 3 void salts and just spent a good half an hour loading and reloading at an alchemist's shop and only got 1...id like to go to a treasure hunter and put a order in for 3 void salts and pay 3000 gold and wait a certain amount of days and go pick them up.....id like it to order almost anything..dont know bout artifacts tho.
