Saw this a few minutes ago, not sure if targeted offer but the web page seems to work in incognito mode.
For those that don't know what Amazon Coins are, it's basically like Google Play Store credit that you use for in app purchases. Categorised in gaming as Amazon Coins are mainly used for IAPs in mobile games such as Hearthstone packs.
[NOTE: Clicking this link will not give you any coins. The Coins offer is only accessible via the Amazon Appstore home page when you are logged in. Not all users are eligible and certain conditions need to be fulfilled.]
Mod: This is a targeted deal. To hide targeted deals in the future, click the hide link below and then check targeted deals. See this thread for more information.
