That's right. Electronic goods from USA and Europe are different, the adapter and the volt.
I heard that big stores like Mediamarkt in the Netherlands are using distributors from Germany. And the prices they buy the goods are not much different than from the USA.
Maby you can search in Germany for the distributors.
It would be wise to look for distributors of consumer electronics in Europe itself.
But if you are looking for other goods like memory cards, bluetooth dongles, etc
you can also search the Chinese or USA market and look for the best quality and prices.
