“The lesson [that our research revealed] from e-tailers: They, too, can reap rewards from managing demand-in their case, by segmenting customers according to how they want their goods delivered.

“People who shop online can differ greatly in what they’re willing to pay for delivery, and how flexible they can be on the time and date, when they have to be home to receive the package.

“If e-tailers adjust their fees and delivery options accordingly, they can not only increase revenue but also efficiency.” Niels Agatz, PhD candidate at the Rotterdam School of Management | Wall St. Journal, 7 July 2008
