both of my addons are "non-traditional" and they are very helpful/powerful (some people consider them "essential" addons) in helping you make the most of your guild sales.
If you are not familiar with the other addon it's Guild Sales Assistant for Master Merchant .. there is a tutorial on how to install it and a tutorial on how to use some of the advanced features.

Advanced Features Guide:
I should mention that neither addon will work if you aren't using Master Merchant because that is the addon that it pulls the data from.
GSA is for your sales and your sales only
GSM is for all sales for all the sales guilds you are in
If you have any questions or problems you can /w in game @dopiate ... I'm only on the NA server but I check my mail at ESOUI.com also.
