Right now, when you look at a listing of items, there's a column with the "price" and next to it a column with "shipping."
I think it would be nice if there was a way to highlight (Maybe a different color? Bold? Additional text?) those listings that include the "discounted shipping for multiple items."
For example, I sell stamps, and most of the time I will sell more than one to the same buyer. When just glancing at the lists of items for sale, it would be nice to be able to tell which listings are from sellers who offer shipping discounts... I would be more likely to click on those and look at a seller's other listings.
