International packages are hard to track unless the sender sent them via registered mail. Learned that the hard way.
Some schmuck in GER did a reverse payment on me and decided to keep the jawnz I sent him. I thought I covered and talked shit to him about how paypal would side with me.
I was wrong. I got screwed, because package was not traceable outside the U.S., despite having a tracking number and a custom number. Now I always ship registered mail. Its an additional $10 but its better than losing both your money and your jawnz.
I so sad. I had never been screwed over before then.
