Yep, VAT (sales tax) is never included on prices given in the US. You have to wait until you check out to find out how much sales tax you have to pay. In most EU countries (and the Middle East) VAT is included in the sticker price.

In addition, don't forget about import tax that the local country may charge on top of VAT. I'm currently living in Amman, Jordan and VAT is 16%. On top of that the import tax for goods from America, Europe, Japan, etc is close to 24%. That's 40% extra that has to be paid above the US price (which is not discounted).
