Literally overnight, the prices practically doubled in several regions. WoW Tokens in North America have spiked from 59,000 gold to 112,000 gold (and is still climbing), while Tokens in Europe are around 200,000 gold at the time of this writing. China rose to 289,000 gold for a brief period before coming back down a little.
“It isn’t really worth converting tokens to 30 days of game time at the moment. It’s best to convert them to Battle.net Balance and purchase 3+ months via web shop,” World of Warcraft site Icy Veins recommended.
