No, it is necessary to set the product price zero while creating bundle products in your ecommerce store. However, it is recommended to set the product price to zero. You don’t need to add the price of the parent product as the price of the product bundle is calculated on the basis of the sum of sub-products’ price.
On the other hand, suppose you have set the master product price higher than zero and created the product bundle in your e-commerce store. Now, when the bundled product is added to the shopping cart, the price set for the master product gets added to the individual items. So, it is recommended to set the master product price to zero while bundling the products.
