Hello,
If by Sale Page, you mean the Page where you can find all the Products that are on Sale then we would recommend you to create a Category named “Sale” on your Site under the Dashboard > Products > Categories.
Then tag all the Sale Products in that Category > and then when you view that Category page you would’ve all the Sale Products there.
Further, the Theme provides the option of creating Custom WooCommerce Layouts using the Theme’s Layout Builder. You can check the Guide regarding that here: https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
Hope this helps !
Best Regards
