That's great :) I have to buy online either way. We have 10% coupons floating around most of the time, but I think in other countries like Austria and I believe Poland there are even 20% coupons sometimes, which I'm jealous of too.
I think most MAC products are 1-2 Euro cheaper in the Netherlands compared to here, so even with the 10% off it's not that big of a difference.
That's true that the products are more expensive in Germany. I once bought a EDSF in Glorify in a Douglas in Germany and it was without discount 50 cents more, but with discount over 2 euro's cheaper, so I was lucky then. It could be worse indeed.
