shellygrrl's suggestions are great. :)
Another non-US-based website (it's british):
It's true that it's less expensive in the US but if you take into account shipping costs and possible taxes (or mandatory taxes depending on the websites and carriers), a NARS blush bought in the US and shipped within Europe costs more than a NARS blush bought within the European Union.
Anyway, US-based websites:
For example, I added a NARS blush to my cart at Barneys and Nordstroms and asked for shipping to the Netherlands. A blush is about 24€. Shipping is 26€. Duty and VAT are close to 8€ and added automatically. You'd pay 58€ for a blush.
If you really want to save money, I think the best option is either to buy from HQHair, or narscsometics.eu or through the french Sephora website. Sometimes there are discount codes for the french sephora website (I can help with that! ;) ) and HQHair. Not for narscosmetics.eu
