Promo codes are a great way to get additional savings at checkout. They can be issued by the seller, as well as Customer Service directly through Amazon. You can also find them on those digital coupon websites, but they are not always an extra discount. Sometimes they are simply the sale price currently being offered on Amazon, so don’t waste too much time trying to track down an extra code.
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.
