It's still in "test" but the new consignment systems looks great!
Currently you have up to 6 slots to place containers in to hold your items.
You then simply drag and drop the items onto the broker sell window, set your price, and walla your now selling via the consignment system...
Only down side for those who use the ThorUI is that SOE appears to have removed the sales window completely therefore you may no longer search for price comparisons automatically. (I'll see if I can develop something for the new consignment window)
