Drop adress

Maybe use reship?

It can be hard depending on where you live but look up empty houses in your area (for ex houses that are waiting to be sold). Assuming your packages do not require signature you can send them there and pick them up. Reships can also work but it is harder to be anon.

You can search for a P2P reship for Germany. Then you can just use that.

If I use a reship I have still to give a adress and a name.

But you can use fake name

For me one of the best method to safety receive the parcel is to use fake name and use address near my house, then i'm calling to the carrier and telling him to deliver to other address or asking him if we can meet outside. You can use many excuses. Hope this will help you.
