A method of allowing access to a receptacle for securing a package includes: sensing an opening and closing of the lid; activating, in response to determining the lid is sufficiently closed, the lock mechanism to transition from the unlocked state to the locked state; scanning an email message in a user's email account to identify a reference or tracking number of a second package; parsing the email message to obtain a delivery code; receiving entry of the delivery code; activating the lock mechanism based on entry of the delivery code to transition from the locked state to the unlocked state; sensing a second opening and closing of the lid; activating the lock mechanism to transition from the unlocked state to the locked state; receiving information corresponding to entry of an access code; activating the lock mechanism to transition from the locked state to the unlocked state.
