The availability window for acquiring a pre-purchase bundle for Hearthstone is finite. These offers are typically accessible from the time of the expansion’s announcement until the expansion’s official launch. For example, if an expansion is announced six weeks prior to release, the pre-purchase option is likely to be available for that six-week duration.
Securing a pre-purchase offer allows players to acquire card packs, cosmetic items, and sometimes early access to specific game modes or content associated with the upcoming expansion. This can provide a significant advantage at the expansion’s launch, allowing players to build competitive decks more quickly. Historically, these bundles offer a cost-effective method to expand a player’s card collection compared to purchasing packs individually after the expansion’s release.
