Its not the post office, its Netflix. They are deliberately not crediting my account for days.
Why would they pick on you? I’ve been with netflix since close to the beginning, I’ve been throttled, I’ve been not. In my experience if there’s repeated long delays when I haven’t “earned” throttling the problem is with the delivery part, usually a bad postal worker, usually a temp person covering vacation. Irregular delays usually track to using a particular box. In theory there could be something going wrong at the Memphis netflix office, but that seems kind of unlikely, netflix is notoriously ready to fire people for under performing.
