Hi
Would you pay to have GPS included in your shipping? i.e determining the exact location of the product at any point in time.
I was thinking of buying a disposable GPS, store it in the box (large high value items), so I know where they are at any given time. Costs about an extra $20, but if I send the GPS back i get $10 back.
An actual GPS unit isn't that expensive. Usually the expensive part of the tracker is the SIM, the data service, and the mobile radio chip you need to send information about the location to somewhere useful.
Plus, risk during transit is borne purely by the seller anyway, so there's no benefit to the buyer in having the GPS, and neither will the GPS allow you to do anything in most cases. If it's damaged in transit, it'll still arrive damaged. If it goes missing, you still won't receive it.
PLUS a GPS needs open line of sight to the sky. How often is a package being delivered - via shipping container, delivery vans, air freight, etc, ever going to have that? (Also - re: air freight - will your GPS tracker automatically go into flight-mode if it gets on an airplane? It would rather defeat the purpose if it crashes the plane it's being transported in. You might be able to find the location of the Lost Island though…)
