@MosephineT, as @Alcaro said, the timer will keep ticking, even if you have your Stash Outpost in your inventory. :)

Hi @Monohr i'm afraid the Stash Outpost is only offered towards the start of the Event and due to the Expiry on this, it won't be offered again! There may possibly be some more offers that could help in the next few days such as Event Currency Offers though so keep an eye out!

Kind Regards

Herodite.
