An alternative option for rewards instead of vouchers is the points discount on checkout.
This is a more simple, traditional points redemption method that does not require setting up individual rewards.
With this option enabled, customers can easily redeem their points for a discount on the cart or checkout page.
Simple toggle on the “Enable Points Discount” option in the “Rewards” settings tab, and customise the options as required.
Your customers will then be able redeem any amount of points they have earned on checkout for a discount.

This will also be visible on the cart page, rewards account page, and floating rewards widget.
