You are charging £600, not Asus. If you could had this on "this week only" at ~£580 and competition had this at £539 for one day, there is lot to go down.If Asus can charge £600 and it sells...
You are the salesman, pretty good one probably, but I really think, well hope, I can get Asus Rog Swift at £500 soon, as new, more advanced screens hit the market.
