I think the solution would have to include some sort of logistics where a last mile delivery driver can pick up a return when in the area dropping off a package, meal, or whatever.

Think like how the mailman delivers mail to our homes but at the same time if you put your red flag on your mailbox up, they will grab whatever mail is inside and deliver it to the post office for you.

So that but for packages.

A few things to consider would also be, how often are frequent are these returns needed, and what is the value of these returned packages on average, and if there is a way to generally know the value of the package or what is being returned exactly.
