Originally designed for wow-classic
All grey items with a vendor price are automatically sold when you open a merchant window.
If you want to prevent a grey item from being sold, run slash command:
/vtm keep <itemlink>If you want to automatically sell a non-grey item, run slash command:
/vtm sell <itemlink>This sell command is very useful when farming dungeons for gold!
If you want to undo a command, sell and keep are opposites of eachother.
/vtm debug <itemlink>Will display information such as the item's ID, SellPrice, if it is grey or not, and if the item would be automatically sold.
