I mistakenly yesterday thought the the sale item for today was Shared Storage, which while cool and helpful isn’t nearly as cool as the actual sale for today which is Shared Wardrobe space at 497 Turbine Points! So if you still have all your festival clothing in your packs or personal vaults here’s a chance to get 10 more slots to share between all your characters. The reason I feel it is more valuable is the fact that you can store color variations there too, and only take up a single spot.
I just noticed this when trying to buy the shared storage and was quite excited when I was able to clear out so many of my vaults!
