That's the new way the loot crate. The old way loot crating was unofficially done. I don't think they've got anything setup to show you what's in your loot currently. Maybe something they can look into.

Can't remember the date but after whatever date it was, you select it during purchase for free shipping, or other paid options to have sent when it arrives. After 4 items arrive in your crate, they get sent i believe.
