Now it costs 4999 coins tho I'm not sure that the 20% promo is still active. But you can see it when you try to check out that you will get any coins back or not.

You purchase Amazon Coins from Amazon directly, which you then use in the Amazon app store to purchase P&D Stones, and receive a rebate of coins, which you then use to buy more Stones. Unless there is a work around, you need to be using an Amazon tablet to spend the Coins on Stones.

Similar promotions were offered in the past and, for example, Hearthstone players were able to get packs at like 60+% off.

Ok Cool. Would you be willing to send me amazon coins instead?

I'm looking for 2500 amazon coins. I can do it with a gift card but it's easier for me if I can directly get what i'm after. Let me know.

you have to buy coins first

http://www.amazon.com/Amazon-500-Coins/dp/B0096E8CQA

Yeah they can be a pain to get to. Here you go.

Anyone with a PC should be able to get an Android emulator, this subreddit has a ton of guides on things like that if you use the search function to find one you like.

You can buy the coins directly from the PC website: http://www.amazon.com/Amazon-500-Coins/dp/B0096E8CQA

After that, just use the emulator to run Hearthstone downloaded from the Amazon App Store (getting free packs for using an Android in the process) and use the coins for the discount.

Yeah it's a bit tedious, but it isn't like you're locked out from doing it.

What do you mean from the battle.net client? If you mean opening hearthstone from your pc and getting the discount, then no. You need to have the amazon version of hearthstone installed on your android phone or tablet and buy amazon coins from here. Once you have the amazon coins, you have a choice to pay with coins while checking out your packs from your android device.

I managed to purchase 144 packs for $80 all from my Windows PC w/ Intel. Also a good way to get the free Classic pack buy completing a match.

1. Install DuOS-M (Android Tablet Emulator) from http://www.amiduos.com/
2. Restarted computer and went into the BIOS and enabled Intel Virtualization Technology
3. Launch DuOS and you should be greeted with the tablet home menu (if not your PC might not be supported or you didn't enable the VT setting in the bios)
4. Go to the Amazon App store in DuOS (the app should be on the bottom left of the home screen)
5. Login your Amazon account and search for Hearthstone. Proceed with the download and it should install on the home screen
6. Launch HS and login your account. Make sure you're able to access the Shop.
7. Minimize DuOS and go to your desktop browser. Go to this link http://www.amazon.com/gp/product/B0096E8CQA and buy 10,000 coins for $80. Shouldn't take long to load into your account once the purchase is finalized.
8. Go back to DuOS and back to the Hearthstone shop
9. Choose the GvG packs (NOT CLASSIC) and purchase 40 packs for 5,000 coins (each 40 pack you purchase will earn you an additional 2,500 coins for free) This applies to US accounts only I believe and you should see some confirmation of this before. Do this three times (bonus coins can take up to a minute or so to be added to your account)
10. You should have 120 packs now as well as 2500 coins left.
11. Buy 15 packs for 2000 coins which earns you an additional 1,000 coins for free
12. You should now have 135 packs and 1500 coins left to spend. Use the remaining coins to buy a 7 pack and a 2 pack
13. You should now have 144 packs with some spare coins left

then u have to purchase from the amazon website http://www.amazon.com/Amazon-500-Coins/dp/B0096E8CQA

Since you mentioned you can't buy coins on the website.

Does that mean you can't see this?
