If you manage a WooCommerce store with a meaningful product catalog, you have almost certainly wanted to run a promotion on a specific product category at some point, without having to touch each product individually.
A category discount lets you do exactly that; you get to apply a single rule to every product within a category, instantly.
WooCommerce gives you a partial path to this natively, but if you want access to the full capabilities of a category discount, you will need a dedicated plugin.
Why WooCommerce Product Category Discounts Are Useful
WooCommerce category-level discounts are most powerful when your catalog has natural groupings that align with buying occasions or inventory goals.
For example, if you own a clothing store and are running an end-of-season clearance sale, you wouldn’t want to mark down 200 individual products; instead, you would want to apply a discount to everything in the "Summer Collection" category.
Category discounts also make promotional management cleaner over time. When you add a new product to a discounted category, it automatically inherits the discount. You don't have to remember to apply a separate coupon or sale price to each new item.
Category Discounts in WooCommerce's Native Coupon System
WooCommerce's native coupon system does allow you to restrict a coupon to a specific product category. In the Usage Restriction tab of any coupon, there is a Product Categories field where you can search for and select which categories the coupon applies to.

This effectively creates a category-scoped discount. Customers who enter the code at checkout will receive the discount only on products in the specified category; other items in their cart won't be affected.
The limitation of setting up category discounts this way is the same as with all WooCommerce coupon codes: the customer has to manually enter the code. A category promotion that requires code entry depends entirely on customers discovering and remembering the code before checkout, which limits its reach.
Setting Up a WooCommerce Category Discount With Elevated Discount Rules
Elevated Discount Rules allows you to set up a WooCommerce category discount that applies automatically without the need for customers to enter any coupon codes.

When you’re creating a discount, you’ll see a Category filter within the product scope settings. You can select the category you want to target, configure the discount type and amount, and then save the rule.

From that point forward, every product in that category receives the discount automatically whenever a customer adds one to their cart.

You can also exclude specific products from a category discount if there are items within the category that you want to hold back from the promotion. The exclusion option is available in the same configuration panel.

You can also combine your category discounts with any other active rules that you have created (with priority settings controlling which discount takes precedence), and display messaging can be added to product pages within the discounted category, so that customers know about the offer before they add anything to their cart.

Final Thoughts
Setting up a WooCommerce category discount natively is possible, but the code-entry requirement limits how effectively the promotion can drive conversions for your store.
If what you need is a category discount that applies automatically at scale and offers full control over exclusions and messaging, Elevated Discount Rules is the right tool for the job.
