There may be extra money in your closet, and not just the kind you find hidden in your pockets from the last time you wore or used the item! If you are like many and have clothing, handbags and accessories in your closet that you have not worn in a some time, or you are simply tired of wearing, you can easily sell clothing, jewelry and purses through your iPhone, iPad or iPod Touch (not yet for Android users), using the app Poshmark.
