1. I have had problems with the mail. 2. I use to work for fedx you would be sup-prized where exp. little envelopes can squeeze. for example working for fedx a package was found on a lard cargo bin (this is what the store all packages to be shipped to states) not every one places the in the large bins. some ass hole will throw them lol) Some one threw an envelope and it went above the crate and wedged on to the top of it. keep in mind there high the only time the top is looked at is there inspection. witch is may be every three months. Sy for rambling but you should all ways use tracking. Just trying to help you cover ur butt lol .
