HURRY, GET IN ON THIS FAST!
This is legit and worked for me! Amazon is giving away a free $5 credit for downloading a free app.
Go here and opt to download one of the qualifying free apps (continue even if it gives you a message saying it won’t work on your device because you aren’t required to actually download the app to get the credit). – If you don’t have a device that it will work on, you can add it to your cloud.
Add anything to your cart at checkout and your $5 credit will automatically be applied.
If you can’t use your device, do it from a computer, that is where I did it.
