I have a PW3 & a Fire 10 5th gen I am thinking of trading in. Can I use the Money & Buy a New Fire? I don't want any more Kindles from Amazon I seem to have the Worst luck with them... 9 month after I get them they fall apart!

That's why I want to use the Money & Bonuses on a Fire.
Does Anyone know IF Amazon will allow this? Have you done it? If so how did it turn out for you?
