Discount Master builds discounts as rules: you define what the discount does, when it applies, and how it looks to customers. A rule fires automatically whenever a cart matches, with no coupon code needed. This guide walks you through the four-step wizard by building a simple example: 20% off a product category.

The four steps

Every discount is configured across four tabs: General (name and schedule), Actions (what the discount does), Conditions (when it applies), and Display (how savings are shown).

Step 1: General

  1. Open the wizard Go to Discount Master › Discounts › Add New.
  2. Name the rule Give it an internal Title such as Winter Collection 20% Off. This is admin-only and never shown to customers.
  3. Set a schedule (optional) Add a Start Date and End Date to have the discount activate and expire on its own. Leave them blank to run indefinitely.
  4. Activate it Turn the Activate toggle on. Inactive rules are saved but never applied.

Step 2: Actions

The action is what the discount does. You can add more than one row; each is applied independently.

  1. Add an action On the Actions tab, click Add Action.
  2. Choose the type and amount Select Product — Percentage off price and enter 20 in the amount field.
  3. Target products (optional) Leave the Products field blank to affect all products (we will narrow it to a category with a condition next), or search and pick specific products here.
Free vs Pro actions

The free plugin covers product and cart percentage/fixed discounts and BOGO. Pro adds shipping discounts, apply-coupon, free gifts, and tiered pricing. See Discount Actions for the full list.

Step 3: Conditions

Conditions are when the discount applies. Every condition must be satisfied for the rule to fire.

  1. Add a condition On the Conditions tab, click Add Condition.
  2. Choose Product Categories Select Product Categories, leave the toggle on Include, and search for Winter Collection.
  3. Leave the rest open With one condition, the 20% now applies to any cart containing a Winter Collection product. Add more conditions (cart subtotal, tags, and so on) to narrow it further.
Include, Exclude, and logic

Each condition has an Include / Exclude toggle, and multiple conditions can be combined with AND/OR logic. See Discount Conditions.

Step 4: Display

The Display tab controls the cosmetic indicators customers see. These never change the calculation itself.

  • Tick where the discounted price should show: single product pages, product archives, cart, and checkout.
  • Leave Show discount action as cart item meta on to add a “Discount: …” line under the product in the cart and order.

Save and test

  1. Save the discount Click Save. The rule appears in Discount Master › Discounts.
  2. Test it on the storefront Add a Winter Collection product to the cart and confirm the 20% is applied automatically, with the crossed-out original price and the savings shown.
When several rules match

If more than one rule applies to a cart, they are evaluated top to bottom in the Discounts list. Drag rows to set priority, and use the stop-processing flag to prevent rules stacking. See Managing Discounts & Priority.
