About This Solution

This is a bit of a weird one but there’s some interesting marketing psychology to it…

Amazon allow customers to apply a coupon by checking a box on the product page.

Why not just automatically give the customer the discount though?

Amazon’s tactic to display a coupon option, instead of just automatically showing a discounted price, gives shoppers an extra incentive to make the purchase right away.

This kind of psychology is explained more in the WooCommerce Conversion Rate Optimisation (CRO) eBook.

Back to this snippet, when implementing this code, customers will be able to apply the coupon to their order when the box is checked and the product is added to their cart.

Don’t forget to first create your coupon and second replace my example one in the code.

add_action( 'woocommerce_after_add_to_cart_button', 'ecommercehints_coupon_checbox', 10 );

        $coupon_code = 'YOUR_COUPON_CODE_HERE'; // Replace with your coupon code
        $coupon = new WC_Coupon( $coupon_code );
        WC()->cart->apply_coupon( $coupon_code );
    }
