Of course what's even more efficient is shipping to a network of distribution centers which are in walking distance for most people, reachable by mass transit by others and reachable during trips that would have happened anyway for the rest.

You assume that waking productive human time (spent walking to/from the distribution center, or waiting for mass transit connections) is worth absolutely nothing.

It's the scarcest resource of all of this.

I didn't assume that, I simply didn't discuss it. I was replying to the grandparent which refers to environmental issues.

Do you mean that we would pick up from a large warehouse, or that the warehouse would ship orders to central distribution points?

I think morsch means supermarkets, farmers' markets, high streets, and shopping malls.

really? aren't most trips to a store to buy multiple items? a drive to a nearby store is as bad as shipping the product from amazon's warehouse to your address?

also, packaging. both the process and the materials.

Do you go to the store to pick up items for everyone in your neighborhood? If not then you're shockingly less efficient than UPS.

yes, but obviously that's not the comparison. shipping services have much longer distances to travel, they have the overhead of the entire system (trucks or planes for the long haul, trucks driving to your delivery address and from the pickup address, the associated costs of all the time spent by all the people involved) to overcome. i'm not sure who exactly wins in the end without real numbers.

and again, packaging should not be underestimated either.

Your goods come from somewhere regardless, and whether they are delivered to a store or to your home they have to travel that distance just the same. But with delivery trucks the miles driven by the trucks are amortized over all of the deliveries made.
