I keep running into Dutch e-commerce sites that advertise prices without fees and VAT, and I haven't figured out who I'm supposed to complain to. Just yesterday, the first indication the prices weren't accurate is when I saw the real total in iDEAL.
Edit: not saying your lying, just thinking it might be geo related sometimes?
Examples I remembered offhand: elektramat.nl, rvspaleis.nl
Those both list the price with VAT too, but the primary list price is without.
You'll find plenty of more examples e.g. if you think about what the house you're in is made of, and look for those materials in bulk. E.g. I-beams, pallets of wood, insulation etc.
I know that at least a few years ago they were actively and aggressively enforcing these kind of transparent pricing legislation, although I don't know the current situation, or what they do with tips sent to them.
