Hi Ajedrezon,

#1. Regarding tax rate:

When you use automatic pricing for a bundle, prices, and taxes are calculated from the bundle's child products. Conversely, when you use fixed pricing for a bundle, prices and taxes are calculated from the main bundle product. You can switch between 2 pricing modes here:

#2. Regarding shipping fee:

Similar to the pricing above, you can also switch between the two shipping calculation methods here:

Our plugin doesn't calculate the weight automatically since it can be changed when the buyer changes the variation or quantity of bundled sub-products.

Suppose you use the predefined bundles only and want to calculate the weight for bundles; please add the custom code below. (How to add custom code? ↗):

add_filter( 'woocommerce_product_get_weight', function ( $weight, $product ) {
	if ( $product->is_type( 'woosb' ) && ( $items = $product->get_items() ) ) {
		$woosb_weight = 0;

		foreach ( $items as $item ) {
			$woosb_product = wc_get_product( $item['id'] );

			if ( ! $woosb_product || $woosb_product->is_type( 'woosb' ) ) {
				continue;
			}

			if ( $woosb_product_weight = $woosb_product->get_weight() ) {
				$woosb_weight += (float) $woosb_product_weight * $item['qty'];
			}
		}

		return $woosb_weight;
	}

	return $weight;
}, 99, 2 );
