People keep acting like VAT is unique outside the united states. In the US, we have sales tax. It varies from state to state (and county to county). But you can easily pay 7-10%. The sticker shock in Europe is ahead of time and in the advertised price. In the US, you get the shock of seeing how much you are really paying right as you are clicking order or swiping your card at a register.
People (read: me) are not acting like VAT is unique outside the US. I’m a regular visitor to the US and I know exactly how much sales tax is added at the point of sale. Now, correct me if I’m wrong but there is no US state where sales tax is as high as 20%. My point was simply to remind commenters from the US that prices charged around the world may be significantly more than they are at home and that may account for at least some of the perception of overpricing.
