If you are unfortuante enough to live somewhere where the Sales Tax/VAT/GST (or whatever you call it) is not included in the labelled price, how do you think about the tax when you are shopping? Do you automatically add a bit on in your mind when you look at a price? Do you get a calculator out when you are going round the store and work everything out exactly? Or do you just not bother thinking about the tax and accept that the price at the checkout is going to be a bit more than what you are expecting?
It seems like a stupid system to me, why don't they just include it in the price?
