To create a discount campaign, navigate to "Action" for your desired collection in Rusty Collections. Then select discount at the top of the table. This will open up a form to create a new discount campaign. Name your discount campaign. Then you are required to select a date range. You can have the campaign start immediately or schedule the start time. Also, you have the choice to end your campaign at a desired time or have the discount run permanently.
Also please make sure to add the discount percentage (the amount taken off the usual price)
The campaign info will pop up in the Campaigns page and can be turned off manually from this page.
