Department promotions are promotions that affect an entire department of inventory. If you want to learn how to set up departments, see How to Add a New Department.
1. Go to Operations > Inventory > Department Promotion.
2. Click the New button to start a new promotion.
3. Highlight a department, for example Tableware, then enter a percentage value at Percent Off (in this case 20). Choose a Start From and End After date for the promotion. You can restrict the promotion to members only by selecting a membership group from Members Only List (for example, VIP).
4. Click on Save and then Quit to finish. Now every item that belongs to the Tableware Department will have a 20% discount to VIP members if sold between the set dates.
