Instead of sending to your doorstep, you can pick an Amazon Locker in over 50 U.S. cities.

I do not like the security of this apps. By default any one in my home can just open it up and start buying things on my account. I would like it to just add things to my cart on the TV and them buy on "My" Computer or "My" phone. I know you can setup a PIN for "videos, purchasing and certain types of content".But, you then need to enter the PIN for $0 videos. Also, anybody with access to the Fire TV remote can just install the apps and start buying things, no pin, no password, just because you have a Fire TV setup on your account. Amazon you need to have a separate PIN for Buying videos, parental control (ratings), Apps and Shopping. And by default the app should setup a PIN.
