This picture demonstrates why the Postmaster needs reworking to allow valued items to be locked allowing other items to pass through to deletion, a bigger save area, or a priority system where Exotics take prescenence over Legendaries and they over rare, other valuable items cannot be pushed out. There has to be a better way......... I used a key at the end of Nightfall and got a Grasp of Malok then ran the Weekly Heroic, I did not realise that all the blues would fill my Postmaster to capacity, I didn't think there was that many on the ground even though I solo'ed most of it, but even so I used the key and that put the weapon in the PM and then added all the junk !! Not good, not fair, and another downer for a game that needs sorting out, we need space, lots of it, Inventory space, Postmaster space, Vault space, or deleted stuff available for un-deletion for an hour or two at one of the vendors !!!
