Unlike ISP service, parcel shipping is already dirt cheap. Amazon has already had a large impact in that space by pushing its carriers to optimize and making things like Prime possible, but I'm not sure what they could do for parcel rates at retail.

Automated trucks are probably going to be the next big thing that could potentially decrease retail shipping costs (at the expense of laying off all those truck drivers).
