Game monster. Net serious?

There's an offer for the Nintendo Switch on the Game Monster page. It is set here in the new version of 2019 with The Legend of Zelda and Mario Kart 8 Delüx. The price seems to have dropped from around 450 euro to around 250 euro.

How serious is the site and the offer in your opinion. And does anyone know where you can watch reviews?

Sounds more than dubious, for the price you can only get a used one with two games and even then it would still be cheap.
