They say they take care of the taxes, but it's not true. When my package arrived in my country with a huge delay, I hade to pay almost 200 euros extra for the custom charges. All they do is write for the customs that it's a present with a value of 40$ hoping that the customs people won't open the package, and when they do open it and charge you 35 % of the actual price, they just say read the small print. So they actually don't pay any custom charges
They should warn the customers in the first place before they pay for their orders that they would have to pay 35 % of the price to the customs so that they could make a decision whether to make the purchase or not. But they just trap you into buying the goods from them and then they don't care.
So their "all tax and custom charges included" is a misleading condition.
