Use voice commands to have Alexa search items in your order history and on Amazon's Choice list, and read you the products' names, prices and estimated delivery times. Once Alexa has found you the highest-rated and best-priced products, tell it to confirm your order and you're set. Watch for special promotional discounts that you can use to save money while voice ordering, and always ask for current Alexa Deals for exclusive savings.
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.
