That's what I mean, the list price in the big box is just the mfg, markup and labor. You have to add on $5 to the 'Transparent Pricing' that they put in the giant box in the center of the page, you only see that there is an additional shipping fee if you click thru the little slider or submit an order.
Do they discount shipping for multiple items ordered? In that case I personally think having shipping separate makes sense, as 2 $5 items shipped might be e.g. $16 total not $20.
