there is a good chance your money will never get to its destination.
I honestly don't understand why people think this although it is fairly common sentiment. Why do you say that? What do you think will happen?
No, there is not a good chance the money won't get to the destination. I rarely say this about a gov't organization but I totally trust delivery by USPS. I've used Ebay for quite a few years now, and I can't even remember if I've had something get lost in the mail. OP, I don't think you should do exactly this, but if you put it in an envelope and sent it 1st class it'd more than likely get there. I would go with what that member posted here, which is to send it via Registered Mail.
Don't listen to Amph, he's a tool.
