Once you've placed a Reservation, you can still pay to add items to be picked up and stored until the cutoff deadline. All additions to your Reservation will happen through your account, accessible when you log in at CampusCarriers.com.
To log into your account, go to CampusCarriers.com and click Log In at the top right corner.
You will enter the log in credentials you set up when you originally placed your Reservation.
Once you are logged in, you'll be in your account. Scroll down to the section that says Modify Your Reservation and click the link that says Add more Boxes, Oversized Items, or Packing Materials.
You'll be brought to a list where you can select additional items to add to your Reservation.
Once you have selected additional items from the list, click the Continue button to pay for the items you chose to add to your Reservation.
When your payment for the additional item(s) has been made, the items have successfully been added to your Reservation.
