Prices without VAT are the main listed price on Dutch websites whose primary clientele isn't the end consumer.

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.

Ahh yeah, websites targeting other businesses might give the ex-VAT price the preference. Although your 2 examples still show the price including VAT directly under the non-VAT price.
