Just a reminder, to claim your monthly Amazon Prime Gaming Hearthstone rewards. There are two rewards every month. This month it's a random legendary (from Standard) and three standard packs.
If you qualify but aren't sure what to do, log in to Amazon, go to the Prime Gaming section, select Hearthstone and follow the on-screen instructions to connect your Prime and Battlenet accounts. Claim your rewards, start up Hearthstone and enjoy your goodies!
