I've tried Master Merchant and I've tried Arkadius Trade tools, and unless I'm using them wrong, they don't appear to do what I need.

So, when I'm selling something in the Guild Store/Trader, I have an little excel sheet open, I look at TTC's minimum price, and I put the number in, it then adds the Guild 'Cut' and the other ESO 'Cut' and gives me a price, I then put that figure into the sale, and it's usually either close or a couple of gold above.

I'm not out to look for major money on them, hence selling for the min,

My question to you all (and I'm sorry if it's in the wrong category) is there an addon that can do that for me, maybe give me a button I click that does a little math first, based on TTC figures?

Thanks in advance.
