This feature allows you to create promotions for a set amount of time which can be for a rebate or not. You can create a variety of different promotions/rebates at one time which will automatically expire in the amount of time you define.
To create a New Promotion/Rebate, you will need to perform these steps:
1. Define a promotion group for the items to include in the promotion
2. Select items to include in the promotion/rebate from the Inventory Manager
3. Create the new promotion/rebate
