Name your own price in the Market
All you need to do is, just as with the old market, click in the Per Unit field and enter the exact price you want for your items. (We normally do a Click-and-Drag to select the whole amount shown then overkey it. It just saves hitting the Del or Backspace keys.)
The percentage slider is still available if you want to use it, both in large increments by clicking on the + or – buttons and in small increments by fiddling around trying to drag it.
We also noted in testing this that the stock levels were being correctly adjusted after the offers were made, this being the first time it has happened on any of our farms for at least 36 hours. We haven’t seen this mentioned specifically as having been corrected so we still advise caution so that you don’t inadvertently sell too much of anything when placing multiple offers, but things are starting to look up.
