Does anyone know if i can buy out of date military ration packs and where can i get them?

not many helpful answers so far,as for Mr puma saying out of date rations are destroyed for legal reasons this is pure rubbish,SILVERMANS of london(army surplus store) sell them all the time and contrary to belief military ration packs are produced to stay in date for over 20 years,most big army surplus stores sell the 24 hr dehydrated pack in Various menus and cost around �5 to �6 each,and its worth noting that all ration packs sold off from the army to civilian contractors ,ie,surplus stores carry a waiver that the M.O.D.is no longer responsible for them,if you have a problem getting them then email me for some addresses and phone numbers of where to obtain them
