I keep Ishtar Commander handy and ready while I'm playing via mobile app; if stuff gets sent to the Post Master, you can literally transfer the item from your Post Master to your inventory. You do a few runs of something, then check Ishtar. Dismantle the shit and move on. Point is, we all have the capability to be responsible for our own stuff... And if you don't want to use a 3rd Party app (tho I don't see why because, those apps are 100 times better then organizing and managing your items then the actual game does) just hit the Tower every few runs and check your Post Master. I think we're all more then capable of being responsible for ourselves...(I hope).
