If you no longer want to search for a specific type of offer and/or receive alerts, you can delete the Watchlist for it.
You can re-create the Watchlist should you want to search for that grain in the future. If you want to re-instate Watchlist notifications, you will have to re-create a new Watchlist by doing the following:
Login to your account and navigate to My Watchlists.
Click on the specific alert you want to edit on the left-hand panel.
Once the panel on the right loads with details of that specific Watchlist, there’s a link on the top right to “Delete Watchlist”.
