Let us See what is a Sale tag and how to enable it with our Discount Rules Plugin.
What is a Sale Tag ?
Simply put, WooCommerce shows a Sale badge (a.k.a, Sale tag), when your product has both
- Regular Price
- Sale Price

In the above image,
- Regular Price is $10
- Sale Price is $5
As you can see, the Sale price is lower than the Regular price. So WooCommerce treats this product as on SALE!. It shows a SALE badge on top of the product image.

Default Behaviour
By default, WooCommerce only shows a TEXT.... i.e., SALE!
How to enable Sale Badge in WooCommerce Discount Rules
Please go WooCommerce -> Woo Discount Rules -> Settings -> Price rules --> Sale badge tab.

You can enable sale badge based on two options :
Select your desired option and click on Save.
The two options are :
Show only after a rule condition is matched exactly :
The sale badge will be enabled only when the condition matches.
Let's see it with an example :
You have created a discount rule for Buy 5 or more cap, get 10% off.
Now, the sale badge will be displayed only when the cart contains 4+ quantities.
Show on products that are covered under any price based discount rule :
The sale badge will be displayed irrespective of the condition being matched or not.
Let's see with the same example :
You have created a discount rule for Buy 5 or more cap, get 10% off.
Now, the sale badge will be displayed rightaway even if there are no products in cart.
Customize Sale Tag/Badge
Since Woo Discount Rules version 1.7.7, you have the option to customize the "text" on the SALE! Badge.

The default style supported by WooCommerce is
<span class="onsale">Sale!</span>
You are however free to change the text
Example:
<span class="onsale">OFFER!</span>
or even add a HTML snippet for more advanced customizsation.
IMPORTANT!: Change/customize the HTML elements only you know what you are doing.
My storefront used to have the discount shown on the Sale badge. Why I could not do that now?
The Sale Badge is usually a static text. WooCommerce by default only displays a static text: Sale!
However, some theme authors customize this text within their themes to show a discount percentage or amount.
This is achieved by them through the following calculation
Regular Price - Sale Price = Discount Amount (or a percentage)
However, when using a dynamic pricing plugin like Woo Discount Rules, the discount is based on the rules.
An Example Scenario:
Buy 5 or more products, get 5% off.
In this case, the 5% discount is eligible ONLY when a customer adds 5 quantities to cart.
But if we show a Sale Badge with 5% discount on it, customer will MISUNDERSTAND and will look forward to get 5% discount even when he purchases 1 quantity. But that is not the condition.
If you tell your customer you are NOT eligible for discount for 1 quantity, you will disappoint your customer and lose the sale :-(
That is the reason why we do not display a discount percentage or amount inside the Sale badge. Our plugin will just show the default Sale badge text (Sale!).
Does your theme also have an override ? Do you wish to force override the label ?
