TO CLAIM YOUR FREE DELIVERY, YOU NEED YOUR 4 DIGIT CONTAINER TRACKING ID.
This tracking ID is located on the back of your container as shown in image to the left.

Why do we track each container? We use this ID to track important data on how often and where each container is being re-used. By registering your container, you are helping us improve on how we do things, and helping us to measure our environmental footprint.
