Specifically for making profit at the auction house. I'm not sure if there is such a thing, so I will try to explain what I mean first.
Lets pretend I'm on my enchanter, I want to produce an enchant scroll. My current process is to add up the cost of materials (6 abyss crystals, 6 greater cosmic, 40 infinite dust). I look up the prices of these materials, and I find abyss crystals are 43g each, greater cosmics are 14g each, and each stack of infinite dust for 33g. My current process is slow, partially because I'm not great at math, partially because this is manual. So I add them up like (6*43)+(6*14)+(2*33)= 258+84+66= 408
I'm looking for some addon that can take live prices of materials, add them up and give me a "total cost to produce this item" price. So I could go through my list quickly, see the Massacre enchant costs 408 to produce, Berserking costs XYZ and 81sp to Staff costs ABC. My way is slow, and I repeat it a few times a day on a few different professions. If there is no such add-on its not the end of the world, but I just figure I'm not being very efficient right now.
