Make sure to move the item to the party member who will get the best price first, maximizing profits and tripling UI tedium.
DOS2 initially had the same issue with having to move over ridiculous amounts of loot to your designated barterer to maximize profits. The inventory mini-game was the most tedious part of DOS2 and I'm disappointed they decided to go with a convoluted system yet again in D&D which is supposedly much less loot driven.
