I have a DPD delivery today. I can see an hour window when I need to be home, who is delivering it and have options to change the delivery day or request my neighbour gets it all from a simple online interface.
They truly are the kings.
Edit for clarification: my DPD delivery today is NOT the watch!
I also like the 'leave in a safe place' option. When I know I might miss them by a few minutes I tell hem to leave on porch and they even take a little photo of where they left it
