It doesn't make sense unless:

1. The already made out Money Order is for $2,000.00
2. You bite on the scam
3. You send them the "change" from a $200.00 eBay purchase via Western Union.
4. DHL Picks up the package as they said.
5. You deposit the money order from them and it's a fake and bounces.

You're out a ton of money - no way of finding them. Their Yahoo email address is closed and DHL shows a delivery address to a PO Box and it is reshipped by them somewhere else.

Oh, it will work when all it takes is one sucker to fall for it. Let me find the email and I'll post it so you can see how convoluted it was.
