A "pre-order rule" defines the conditions for switching into pre-order mode and the actions to take while in that mode. Here, we'll configure it to "run a discount sale on the 7th, 17th, and 27th of every month, and sell at regular price on all other days."

(1) Click "Pre-Order Rules" in the app's left-hand menu
(2) Click "Create Rule"

(3) From the popup that appears, select "Pre-order using purchase options"
* Since we're running a discount sale here, we'll choose the purchase options option.

(4) Enter any name for the rule, and set the start date to a past date
(5) For recurrence, select "Monthly" and choose "7, 17, 27"

(6) In the Actions (while pre-order is active) tab, set the cart button text and product message for during the discount sale

(7) In the Actions (outside conditions) tab, set the cart button state to "Show cart button"
(8) Set the product message for regular sale periods

(9) In the purchase options section, check "Enable purchase options"
(10) Enter any text for the "pre-order plan name" and "pre-order plan description" * These settings are also visible to customers.
(11) Under discount, select "Percentage discount" and enter 7%
(12) Click "Save"
Step 2. Apply the pre-order rule to a product
Next, apply the pre-order rule you created in Step 1 to the product(s) you want to run the monthly discount sale on.

(1) Click "Product List" in the app's left-hand menu
(2) Check the products you want to run the monthly discount sale on
(3) Click "Apply Rule"
