Thank you for the feedback! <3

We've just made it possible to move account-bound items to your vault via the inventory options. (Click on the item from your inventory, and the option will show up.)

The ability to move it to the vault via quick-stock is being looked into. It's a bit trickier since quick-stock is bound to our user shops system, and we definitely don't want these items moved into shops accidentally, or to interfere with quick-stocking into shops.

This change will be mentioned in next Saturday's weekly siteupdate post :) (If you're not getting pings for that and want to, join the siteupdate forum group - there is a link in my signature.)

There should be no way to move the item from your vault into a shop. We've tested this to the best of our ability, but if you discover a way to get around this, please file a ticket here and ask for to be notified and we'll address it.
