For the love of portable storage units
This means you will not have to worry about being charged for unused containers or for ordering less than what you might actually need. Then you can just call the company again for pick up after you have filled up the containers. Just give them your most convenient time to receive them and they will move them to the destination you specified. Or you can have them kept temporarily at one of their storage facilities. You can have access to the containers anytime you want in case you decided to have them at their facilities, in case you are too busy just yet.
