Bulk purchase discounts are a very common discount scenario in most online stores.
A typical scenario is:
Buy 6 quantity of any products in the store, get 5% discount
Buy 12 quantity, get 10% discount
Buy 18 quantity, get 15% discount
To create such rules,
Go to WooCommerce -> Woo Discount Rules -> Add new Rule :
After Entering into the rule page, just add the rule name and you can select the Discount Type "Bulk Adjustment" from the Drop-down menu.
Its quite simple, you need to set all products in the filter condition and enter the discount percentage in discount tab.
The additional conditions should be added in the Rules (optional) section.
Here is a screenshot of how the cart page looks with discount applied :
If you want the discount to be shown as a coupon in cart, you can enable the checkbox "Show discount in cart as coupon instead of changing the product price" and enter a discount name.
Here is a screenshot of your cart page for reference :
Similar way, you can apply bulk discount for specific categories or specific products as well.
