Full details available on your local Battle.net shop. For me, in the US it's $20 off BFA and 30% off realm/faction/race changes. https://us.shop.battle.net/en-us/fam...ld-of-warcraft


Of note, buying BFA is a cheaper than buying boosts. It is repeatable as many times as desired (start a new team or two)

The process is

  1. Create a Starter Account from account management ( https://account.blizzard.com/games )
  2. Buy BFA and select the starter account to apply the expansion. Boost is available on any account.
  3. Do NOT add game time or sub when it asks.
  4. Delete Starter Account with an automated ticket ( https://battle.net/support/help/prod...1/878/solution )


If for whatever reason you accidentally add game time or sub, GMs can remove the accounts with a regular ticket, but you likely will have more hassle/time involved.
