Select between package types

Good morning,

I’ve a question regarding the different packing types. When I create a label, I can select the product, but the customer always pays the same price, right?

It does not work, that I have “DHL Paket” and “DHL Kleinpaket”, and if the products in the cart are only small and have a certain weight combined, that the customer will pay less for shipping, right?

Its just up to me in the backend to decide which product of DHL I want to use for the order.

Is that right?
