Until when can i pre-purchase Shadowlands?

The title says it all. When is the deadline for Pre-purchasing Shadowlands. Will I be able to pre-purchase it up until release? Or will I have to pre-purchase it before pre-patch comes.

Hey there HanzoMain420,

Pre-sales for Shadowlands are up until the release date of Shadowlands.

Please post in the dedicated WoW forums, if you have any further queries.
