Marketplace
Looks like good deals on some new and old games.
Others including Civ VI digital deluxe at USD 51.99 (AUD 65), Rainbow Six Siege at USD 23.99 (AUD 30), etc…
Sale end date is a little confusing though. Main Humble Bundle page says Summer Sale finishes at 21 Sept 10 AM Pacific Time.
However when I bought XCOM2 DDE, it says the sale price ends in a little over a day.
Unless they mean individual games have their own discount windows during the overall Summer Sale period.
So to be safe I am putting the deal end date as Sep 14.
In a past sale they had games come on and off sale, or they have a higher discount for a small period of time.
