I had two dnm packages arriving the same day. I didn't have tracking from the vendors on either package but they did show up on myusps like packages normally do. I get a notification saying both packages were delivered so I checked the mail and had regular mail, no packs.
In our neighborhood, we have the big boxes where everyone has to open their box with their own key. I figured that they put it in the wrong box and started freaking out thinking about what would happen if a neighbor opens the packs and calls the cops. I cleaned the shit out of the house and psyched myself up for what could possibly happen.
I figured I would check the mail one more time the next morning just in case some miracle happened and it did. The whole back of the box was opened like the mail person forgot to close it, exposing all of the boxes mail. I looked through the mail in the other boxes and found both of my packs in another person's box. I quickly grabbed them as a wave of relief rushed over me.
Had I not used myusps who knows what would have happened. I would have probably waited 3 or 5 days to contact the vendor to check on the tracking and it might have been too late.
Fucking usps...
More than MyUSPS, thank the mailman for doing a poor job at securing people's mail.
