Kindle Fire owners: Check your accounts for coins

This message was posted on Amazon's site today:

So if you have a Kindle Fire, you should have received 500 Amazon Coins ($5 value) to spend on apps and games.  Note: it says if you wish to purchase additional coins for yourself or your family, you can do so at a discount.  I checked my account by going to a paid app's page and it told me I had 500 coins to spend.
