I live in a high rise building and our mailbox fits only letters , big items are either brought to the apartments' individual door or left in a bigger mailbox which only the postman from USPS AND THE OWNER OF THE APARTMENT HAVE ACCESS. PACKAGES THAT SHOULD HAVE BEEN DELIVERED HAVE A SHIPPING ADDRESS WITH THE APARTMENT NUMBER, WHY can't it not deliver to the door of the apartment. APARTMENT NUMBER User's recommendation: DON'T USE DYNAMEX CAUSE CHANCES ARE YOU WILL NOT RECEIVED THE PACKAGED.
