quite pretty common especially if it isn't registered..that to be blame to the bad post office staff in the phils. they normally open the letter if they think it has money inside...happens to me a lot of times...last 2009 my inlaws sent me a birthday card it didnt come to me then christmas came no card and box received though inlaws says they sent loads...so i went to the post office to complaint and told them i would report this matter to the officer after a week all the cards and box handled to me all openedlucky enough they didnt it nathans chocolate coins lol
