Retainer inventory

[Avidria]

I want to be able to do this from my retainer. If I need to adjust the price of an item that isn't selling, I currently have to walk to a MB to check the price, then walk back to my bell to change it.

No you don't, you can click a button in the top right of the sell item menu and select "compare prices" (iirc, not at my PC for exact wording) from the drop-down
You don't have to run back and forth at all to check prices or adjust them for auctions already posted

The retainer menu system is clunky and awful but that is one problem it doesn't have

Might see if I can add a pic later. I think the icon is like a little paper page looking thing? Should be there in the corner of the adjust prices menu
