UK and EU law requires advertised prices to include all taxes.
The most common exception is things aimed at business buyers, who won't pay tax -- so the Dell consumer website shows laptops prices including tax, and the business site shows them without, but labelled as such.
It means if I buy for business from a consumer site, and I'm logged in with my business account, I see 'ugly' prices like 5119.20, as the marketing-friendly number of 6,399.00 is chosen including tax.
