I did not found anything about this on forums, so I'll just post this here,
When you make the timer for one boss, a chest will spawn, and if you don't need the loot from it, you can shout in trade about it, and people can go in and grab the item for gold, just sold one ring for 4000g on a alt-run when we knew we wouldn't make next timer.
Worked nice and it's some easy gold.
