There is a start and end date option available to present your offer to visitors. This is a great way to create promotions prior to a special event or holiday and automatically shut them off when the special ends.
1. Log into your account. Once in the dashboard, navigate to "Promotions".
2. Once in the "Promotions" page, click on the drop-down button labeled "Actions" next to the promotion you'd like to edit. From the drop-down list, click on Edit Design.
3. Once there, you'll find an area on the left that is called basic settings, there you will find date and time.
4. Remember to log in after the promotion expires to ensure you will have an overlay on your site!
