We would greatly benefit from the ability to list our product's core price and then itemize additional charges like shipping and handling fees as extra line items. These could then be selectable as parts of promotions if we choose to waive S&H charges as part of a special offer. Right now, we're forced to include the S&H charges in the product's core price, which in our example takes it from looking like $297 to $317 (which doesn't look as appealing when advertised).
