Thumb Score: -1

I had all but forgotten the Amazon Appstore existed, but there was a time when a bunch of us were getting a ton of free "Amazon Coins [amazon.com]" and buying anything and everything that was remotely useful.

If you purchased an app that is no longer listed on the Amazon Appstore, you can probably get a refund.

Exs:
Tasker 299 coins
SuperSU Pro 256 coins
Adobe Photoshop Touch 797 coins

Those are just the ones I found quickly that I figured would apply to most.
