The Package Drop Box has been out of order for quite some time. There is a sign informing customers that it is out of order and to use the white and green tubs to leave packages. The tubs are basically open baskets with zero security. Packages get stolen, especially in the early hours (8:00 a.m. - 8:30 a.m.) when employees are not present at the front area.
