Vat at 20% is added to the
end of the purchase, not before, so you have an extra 7.60 pounds added on this product that you do not know about till the end. I am not sure if doing that is illegal, reason being, if you just see a total price at the start, the customer isn't aware of how much vat is on the product, they just see the total cost with everything inclusive, and think no more, tax man likes that, but if you show only pre vat prices, then add it right at the end, the customer gets annoyed when he sees the extra cost they may not of been aware of. Customers then become
very aware of how much extra the item costs due to
vat, the tax man doesn't like that, makes them look bad, hence, if I am correct, its illegal.
I have read this somewhere official, but lost the link, Ill have to check again, otherwise everyone would do it, get em through the door with cheaper prices (ie no vat showing) then put it on at the end,
stealth vat if you like, then give the impression,
look how cheap it would be if it wasn't for the
evil vat man.
