Something is wrong with "World of Warcraft: Game Services - Game Time 180 Days". Right now it is 10,99€ per 180 days. In fact it is 10,99€ but for 1 month (30 days). Few days ago everything was fine.
Fantazyjny Hey, thank you for reporting this to us! The prices of WoW subscriptions are now fixed 👍️
(The same thing was happening with "Game Time 90 Days" product)
