What is the difference between a wardrobe rental and purchase?

In

Wardrobe rentals are $10 each and the crew arrives with them on the day of the move, loads them up and unloads them at the new location. If you’d like to have the wardrobe boxes in advance of the move, we sell them at $20 each. These are yours to keep after the move. The reason they are more expensive is because they would be brand new. We would also have to deliver them in a truck on a separate trip as they do not typically fit into a normal passenger vehicle, which is what we use to provide 90% of our box deliveries.
