I will prefer any of those options over my package having to sit in the rain or on the snow.

What I want is cheaper shipping if they drop it off at a post office or something. For example on Amazon I see it as an option but only ever as a "carbon-reduction" vs just delivering to my front door. I know it's cheaper - pass on those savings to me.
For delivery-to-post-office to be more carbon-efficient than them delivering to your house, the inequality (additional distance you need to travel to get to post office / your mpg) < (additional distance they need to travel to get to your house / their mpg) must be true. If you were gonna drive past the post office anyway, or your vehicle is significantly more efficient than their delivery van, then it might pencil out. If you're making an extra trip, it probably doesn't make sense.
