The cash on delivery and flexibility of couriers is one of the few services that work quite well here, compared to some more developed countries.
Either I need to be home to get a delivery or I have to rely on them giving my parcel to the concierge. Which is often more of a hassle as he finishes at 5 and I'm often not home in time to get my parcel from him.
For example, a service I like is Inpost. They have a few dozen of huge post boxes in each bigger city. About 20 compartments in each. The package is not delivered to your house, but instead you have 3 days to retrieve it from one of those huge yellow boxes. It's a little walk, but you can do it in the middle of the night (they text you with opening code). You don't even have to know the recipient's delivery address, just the phone number and e-mail, and the yellow box closest to them. So in a way it protects privacy.
I'd pay extra for that (for some important or expensive purchases).
