Old habits die hard don't they? It all part of making a product cheaper than its real cost at point of delivery.
Mail order firms also quote 'packing and delivery' at way above actual cost to mask a higher product price.
Having worked in the Auto industry I can quote other 'sharp practices'
How about -metallic paint 'extra'- you try ordering a plain solid colour, ditto alloy wheels or other 'extras' that are built inn the model you want with out the option- its is all a game to make a basic price look keen- but a basic product is not available.
