I think for any of the supplies you pick up let stores know what you are doing. They may either discount or throw more in....

You do know also not to mail it to Iraq?

Each soldier has the equivelant of a domestic address that will be forwarded to them in field. Whether you know his address in Iraq and mail it straight there...or to the army domestic one...it's on the same d*&^ plane so spare yourself the postage.
