When a WooCommerce product is on sale, a tag is placed on top of the Product Thumbnails. The default label for this tag is “Sale!”. 
This plugin allows you to customize the label and can even insert the price difference or percent difference. Examples:
<ul>
<li>Save 20%</li>
<li>20% off!</li>
<li>Save $5.00</li>
<li>$5.00 off!</li>
</ul>

Woocommerce Custom Sale Tag

Customize the sale tag that appears on WooCommerce product thumbnails when a product sale price is set lower than the retail price.
