Due to Covid19 it is literally not possible to send packages to some regions of the world right now.
For example, "the transport capacity to the USA is currently substantially reduced. As a result, mail and parcel service can only be maintained subject to certain special measures." (DHL Information)
That means that it is so very expensive to send a parcel for example to the U.S. (52,99€ at the moment), that it is literally impossible.
Thank you for your understanding, that some orders can not be processed properly at the moment.
Stay safe!
