Best Buy Shadowlands Pre-Order

I bought the Shadowlands Collectors Edition from best buy since the blizzard store ran out of stock. I would like to know how to get the pre order bonuses in game now if that is possible.

You’ll have to buy the digital copy if you want stuff ahead of time. It’ll get refunded to you in balance when you add the physical key once you get it. It’s automated now which is pretty cool.
