L'achat de pack durant la béta est discutable, cependant actuellement voici ce qui est prévu :
Just an FYI, you will not lose the money you spend during beta. Prior to launch your card collection will be reset, and any cards you acquired through a purchased card pack or earned during the beta test will be removed. However, any purchases you made during the beta test will be credited back to you in the form of new, unopened card packs at launch, equal to the value you spent during the beta test. Please note that these will not contain the same cards as those received from card packs in the beta test. Also, as a thank-you for testing out the in-game store during Hearthstone’s beta phase, everyone who purchased a card pack in the beta test will get a special gift.
Pour résumer, si vous achetez des packs cartes durant la béta, ils seront perdus, mais les crédits dépensés seront automatiquement reconduits pour le jeu final. En remerciemments, vous aurez des cadeaux spéciaux.
