> I guess that is why it is not included in the price by default
I hear that argument a lot but it does not really make sense to me. The place of purchase knowns what their tax rate is in their current location because the cash register has that information (and I assume this sales tax does not change very frequently?). So why not print out or display the prices with that tax included?
Edit: Ok I see, the "you" I had in my post was confusing. VAT is charged on the value added at each point of the chain, again unlike sales/use tax.
In Europe they have a 1 euro menu regardless of what country the burger was sold in (countries have different VAT rates). Some advertising is even shared between smaller countries that speak the same languages.
I really don't care, it's their problem not mine. All I want is for stores, fast food places, etc., to be honest about the price I am to pay.
In Europe, including the UK, it is illegal to advertise only tax-exclusive prices to end customers.
If you want to rail against hidden charges complain about the restaurant welfare system that allows employers to legally under pay and fire employees for not making the majority of their money from tips
Obviously it's beneficial to be able to advertise the lower price, these days assembling your own PC from components must be much less common than it was back then so I imagine even if the decision went in their favour back then that's changed since.
