NextGen (Xbox One, Playstation), where is the best place to buy?

Question

Gaming consoles

Good evening everyone!
I was interested in buying a new generation console ( Xbox One or Playstation 4 ), I would like to purchase a console from abroad (I understand that at the moment the dollar and euro exchange rate is far from profitable, but still I need to try to take the console online).
So, as I understand it, the most adequate option is to take the console in these online stores (if there is something better, I would like to hear):
1) Amazon.de
2) Amazon.com
3) Amazon.co.uk
As far as I know, all of them can send parcels directly, i.e. you can not use the services of an intermediary.
Tell me, what is the most profitable way "cheap"?
Thank you for your attention!
