okay so the shitty link says if you spend 23$ for 2500 amazon coins

you save 2$ and get 250 coins back from purchasing BRM????

and then you get 2.50$ to buy packs?

but how much is 1 pack?

cuz it only says 40$ 80$ and i dont want to spend 40 i want to spend 20 for a small boost

every hearthstone purchase u make from the appstore using amazon coins gives u a 10% bonus back. so in this case since its 2500 u get 250 back like u mention. 100 coins is basically 1 pack i think but they do have a coin tax too. 250 coins should be enough for two packs

make sure to download the amazon appstore app plus dl hearthstone from the amazon appstore than purchase it that way or it fucks up if u have the google play hearthstone version

so you have to keep buying packs or pay 40/80 to make it worthwhile?

it's not a flat discount?

not sure where the 40/80 is coming from. i have bought $20 worth of amazon coins before. once u get the amazon appstore version when u go to buy packs in the game like normal an amazon thing pops up offering u the option to pay $ or coins

in the long run buying packs thru amazon is always cheaper than paying blizzard since purchasing the 5000 coins for example (basically $50) only costs $45 than u tack on the extra 10% on the purchases it turns into essentially free packs u wouldnt get otherwise

if i only want to spend 20$ on the game, i still get like an extra pack or two compared to blizz?

Roughly

Yep..
I think there are times when amazon is sponsoring hearthstone events that the discount is a little more as well.
I don't use appstore but I have friends who have in the past for packs. seemed like decent value

Hey you're buying cards. Never would have seen this coming.
