A: Just like any other scene purchase, just go to the bundles section and select if you want to download the scenes, or stash them.
If you select to download the scenes, all the scenes in the bundle will be immediately available for you to download. Simply go to My Account and click on the My Downloads tab so you can check what scenes you haven't downloaded yet.
If you select to stash them, all the scenes in the bundle will immediately be available to play on your stash collection. Simply go to My Stash tab, on My Account.
