PSA: Blizzard Hearthstone 43% Off on Packs (US Residents Only)
This week Amazon is having 23% off when you buy 5000 Coins ($38.50 vs $50), on top of that you get 20% back when buying packs through Amazon Underground installed Hearthstone app. All in all 43% off is the best deal in a while.
Keep in mind, if your state charges tax on digital goods you have to have enough coins to cover the tax. The deal is set to expire sometime today.
