5% on all products + 5% on checkout in WooCommerce - how to implement?

Question

WordPress

There is a WooCommerce store.

• It is necessary to make sure that for each product on the site there is a -5% discount from the price.
  
• Another -5% discount should be displayed already in the cart for the total order
  

Can you suggest any plugin to implement this idea?
Or where to dig in the direction of writing your own functionality? Examples?

Answer 1

How to put a discount on goods is up to you - you can use WP AllImport from CSV to pull up the crown, where the sale_price column is a 5% discount price.
A discount on the entire amount of the order can be made by a plugin for discounting payment methods. , and any other analogue.
