Here at dabs.com, more than half of our sales are from businesses. The computer market as a whole is probably about 90% business, i.e. £9 out of every £10 is spent by businesses, so it's therefore become normal business practice to show prices without VAT (ex VAT).
In the past, we displayed both the ex VAT and inc VAT prices for each product. Now however, it's the customer that decides how they'd like to have their prices displayed.
At the footer of the site there is an option to change the prices shown, clicking this will change our prices from 'inc vat' prices to 'ex vat prices' and visa versa.
