Mine is full. I went from carrying triplicates on some exotics to just one or two to make space. One option is for Bungie to allow u to "download" an item (shader, emblem, ship, weapons, armor, sparrow) that u had previously owned and had deleted. In other words, it is similar to buying a game from the Microsoft store, deleting it to make drive space, and then downloading it again when u wanted to play it again or upgraded your memory to hold more games. Also, it would be nice to delete items in the post office without having to collect them first. I often don't have room in my shader section to pick up the shader from the post office to then delete it. I don't want to leave it there because the icon remains at the post office.
