## Code

```php
$wpide_edd_auto_code = 'SUMMER20'; // Existing discount code.

add_action( 'template_redirect', function () use ( $wpide_edd_auto_code ) {
    if ( ! function_exists( 'edd_is_checkout' ) || ! edd_is_checkout() || ! edd_get_cart_contents() || edd_cart_has_discounts() ) {
        return;
    }

    if ( edd_is_discount_valid( $wpide_edd_auto_code, '', false ) ) {
        edd_set_cart_discount( $wpide_edd_auto_code );
    }
} );
```

## Notes

Create the code in Downloads > Discounts first (its dates and limits still apply) and remove the snippet when the sale ends.
