"Transportation By Amazon" (TBA) used to be a pipe dream and was envisioned as a way to use Amazon's cheaper shipping rates to ship packages of all types.

With the build out of Amazon's own transportation network, Transportation By Amazon is poised to become a reality. The biggest part that remains is the pick-up of packages for shipping / reverse logistics. This should not be too hard, especially as Customer Returns is integrated into Amazon's transportation network.

After Customer Returns is done, it's just a matter of figuring out how to get accurate shipment parameters (box size, weight, type of goods being shipped) and then building a website front-end to advertise and slowly ramp up the capability and learn how to handle different types of exceptional conditions.
