Count me in on this crusade. I'm currently building a site for a client and we're having a hard time figuring out how to handle shipping. Sometimes when their customers purchase mutliple items it doesn't cost any more to ship them b/c the weight difference is negligable and it will all fit in one box. Other times the additional items, which may not cost much, do require their own box and now the shipping costs for the customers have gone up. My customer said that one time the shipping on the site came out to $48, but it only cost them $10 to actually ship it, and that really angers their customers when they receive a box and the shipping lable shows how much they paid to ship it.
I am glad to know that we're not alone... I guess.
