Amazon Coin 20% off back (Hearthstone)
The deal is back for a limited time. If you are not in a rush, you may consider buying with the 20% off and holding out for a 20% or 30% coinback like previous times. (It’s only 10% this time)

Basically, what you need to do is to download the amazon app on your android device (tablet or phone) and using that download the amazon version of Hearthstone.
With that, you can buy amazon coins via amazon and use it to purchase hearthstone packs or expansions in game and get a coinback!
If you lack a device, you can also try a windows android emulator. (iOS and macs have a harder time, the emulators tend to be paid, you could load a windows partition onto your mac or it might be more convenient for you to buy an android device or cheap windows tablet)
pretty popular emulator
(it’s only free for 30 days however, so if you are holding that might not be so good an idea, you might want to prep a cheap android device)
