It's just as easy, trust me.
If you buy small items which aren't worth more than 200 €, they'll simply drop it in your mailbox.
Otherwise, simply make a huge X as a signature if they ask you for one, they won't fucking care.
In my area, they usually bring the package to the next post-office when they can't meet you at your home. That's when you're fucked, as you'll have to pick it up and there are cameras everywhere and even show your ID.
