I bought my Trezor through Amazon from the official Trezor store
Trezors are not available on Amazon.de. I would rather buy from the official company web-sites.
I think in Europe is easier to get Trezor or Ledger from official websites and it's better
But here in Brazil we have to pay almost another wallet in taxes, sometimes the import tax is 90% of the price of product
I bought through Amazon US because when I went to the country it was the best way for me to buy and receive via Amazon locker
Sometimes there are promotions on Amazon that can also be worth it
