This doesn't work consistently (in Berlin at least), especially with Amazon and DHL. There is no guarantee over that the package will be shipped via DHL / Deutsche Post, and I am at this moment dealing with Hermes and DPD refusing to deliver Amazon packages to a DHL Packstation. On top of that, DHL refuses to deliver to their own Postfiliale locations at times, DHL express even explicitly say they cannot do this.
