## Code

```php
add_action( 'woocommerce_before_calculate_totals', function ( $cart ) {
    $gift_id   = 0;  // Product ID of the free gift.
    $threshold = 75; // Cart subtotal that unlocks the gift.

    static $running = false;

    if ( ! $gift_id || $running || ( is_admin() && ! wp_doing_ajax() ) ) {
        return;
    }

    $running = true;

    $subtotal = 0;
    $gift_key = '';

    foreach ( $cart->get_cart() as $key => $item ) {
        if ( (int) $item['product_id'] === $gift_id ) {
            $gift_key = $key;
            continue;
        }
        $subtotal += (float) $item['data']->get_price() * (int) $item['quantity'];
    }

    if ( $subtotal >= $threshold && ! $gift_key ) {
        $cart->add_to_cart( $gift_id, 1 );
    } elseif ( $subtotal < $threshold && $gift_key ) {
        $cart->remove_cart_item( $gift_key );
    }

    $running = false;
} );
```

## Notes

Create the gift as a product priced at 0 (it can be hidden from the catalog), then set $gift_id and $threshold.
