Instead of sending to your doorstep, you can pick an Amazon Locker in over 50 U.S. cities. Just go to 'Manage Address Book' in the settings section of your account, click 'Enter a new address,' and search for an Amazon Locker location using the search fields shown. You can search by address, zip code, landmark or Locker name. You can also add an Amazon Locker to your address book by scanning the QR code on the Locker screen itself.
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.
