You raise an important issue and I will try to answer you as best I can:
At first sight, European prices seem a bit more expensive than iFixit prices in the US. Things change, however, when you take into account that listed prices in the US are always net prices and do not include tax. Residents in the US will pay additional sales tax when buying anything, this is just not visible in the advertised product price. The European system is more transparent in this regard.
When you buy any product from the US while residing in Europe, you as the consumer will have to add your home country's VAT to the price and pay it as import sales tax when your order is delivered to you. VAT rates in most European countries range from 19 to 25 percent - so you'll have to add this to the end price of the goods you are buying in the US. In addition to the import sales tax, there are further additional costs when ordering abroad: In most cases, you will be charged customs fees and also a logistics brokerage fee when your parcel arrives at its destination in the EU.
When you consider that shipping costs are are also higher and that delivery takes considerably longer when ordering in the US, I think that the European offer starts to look quite fair and reasonably attractive. What do you think?
It is our intent to offer our European iFixit customers faster access to the most popular products - at an attractive price, and with a European warrantee.
However, Norway is special.
They are not part of the EU (same as Switzerland), but shipping to Norway is more expensive. So it definitely makes no difference for them where they order.
But it is only Norway, for all other countries it is a better deal to shop at the EU Store.
