Drop is an address which you use for shipping address in carding. Let me explain… ) am carding with a USA CC. if ) use a USA address as shipping address then order will ship 100% & I will be safe. So we have to manage USA address. If we have friends or relatives then no problem. Otherwise there is lots of website that give drop service. We will order in drop address..this website will receive our products and will send to us.. they will take few charge for it. No need for every shopping sites. For hard security sites only.
