Here in the UK, if a parcel is on your doorstep and gets stolen, it's still the retailers responsibility.
This is the law in The Netherlands as well. In fact, in The Netherlands the sender/retailer is responsible (and liable) for delivery to you. If you don't receive the parcel, it has not been delivered. This includes stops in between like a parcel service, but also your neighbours! If the parcel service looses your parcel, or if the neighbour decides to give it to a nephew, the parcel has not been delivered to you and the sender/retailer is liable for the loss.
