Zoltan, You could find out from any of your financial institutions if they issue money orders in US funds drawn on a US bank ( if this is for US purchases).
If so, contact the seller and explain and see if they will take the MO.
Other wise ask your bank on advice of sending US funds.
It also helps if you have a good feedback rating.
This method also applies to purchases in other countries.
