Here, you can select type of items you'd like to apply the discount to (One-off, monthly, quarterly & annual). The discount type (Amount or Percentage) and finally the value of the discount. Click 'Save and Preview' and it'll show the breakdown of the discount in the total section underneath your pricing table.
