It’s 100% the point. It’s such a common and accepted thing here that most sites just have “S & H” during the check out process. To advertise free shipping in the US implies the S&H is free. To suddenly spring a “handling” fee at the last step is deceitful and no different than airlines or hotels advertising a price and then adding a “resort fee” on the last step. And if you think differently, then why do they hide the handling fee until the very last step?

They're a doublet, like "cease and desist." Separating the two makes about as much sense as paying someone an extra fee to "handle" the goods from the warehouse to the supermarket shelf.
