Discount values
The custom discount allows you to specify discount values in a few different ways:
Percentage off - Reduce the price by a percentage (e.g., 20% off)
Amount off - Reduce the price by a fixed amount (e.g., $10 off)
Fixed price - Set a specific price for the item (e.g., $5 each)
Amount off
Allows you to specify a monetary amount to be spread across all qualifying items, or optionally applied to each qualifying item.
Fixed price
Sets a specific price regardless of the original item price. It is only available for repeating discount rules
Apply to compare at price
You can optionally target the compare-at price of targets when applying discounts. Here, discount values are dynamically calculated based off the compare-at price, rather than the actual price of the product. Note, only the 'difference' between the desired discount, and the already discounted value will be applied.
