I believe the post office isn't going to refund 
her in time.  

Well she should ask her family or friends for a 
loan, if that doesnt work, try this...

If she has a credit card, she should call them up 
and pretend she's in an emergency situation, and 
needs them to raise her limit immediately.  Make 
up a story - oh my car broke down needs a new 
transmission, I'm far away from home, I can't 
reach any of my friends or relatives etc 
etc...blah blah blah...

I did this once, Well it was an actual emergency, 
and they hooked me up right away. $350.00 isn't 
alot of money to ask for, unless her credit is 
totally shot, they will approve the request 
instantly.  Then go to the ATM and take it out as 
a cash advance.  

The money order may not be lost, international 
mail resumed delivery on Thursday Sept 27, 
because of the terrorists.  So if she sent the 
payment between Sept 11 and Sept 27, it was just 
sitting in a USPS distribution center pending 
outbound departures.  (I checked the USPS website 
for the news)

In the future, use only registered air mail, or 
International Express Mail.  This mail is  
tracked and under high security, I have never 
lost an article of mail using this method.  FedEx 
and UPS are also alternatives.
