> This is also why the US keeps sales tax separate instead of rolling it into the price of the item like Europe. Even in a relatively federalized (by European standards) country like Switzerland, the VAT is set nationally. This isn’t the case in the US, and several states even have different sales tax rates in each city. It would be a considerable logistical mess to coordinate integrated sales tax signposting, both from a business and consumer perspective. Amazon already handles this somewhat awkwardly by changing store prices if you set your location on Amazon.de to Switzerland, with the prices somewhat unpredictably changing if it decided to remember your location preferences, and no longer following common numbering conventions (e.g. x.99).
