U.S. Postal Money Order (Advice needed..) 
  Hi all..
 
 A chap in the USA has sent me a US Postal Money Order as payment for something I sold on eBay.  It's not of any great value ($27)  What I need to know is, can it be cashed?  If so, how?  My local post office haven't a clue how to handle it!  
 
 Can anyone advise, before I make a fruitless trip to the bank?
 
 Cheers
 Steve
