Also, Prime Day is coming up, so that would be the main reason.Not abnormal. Amazon have regularly chopped 200-300+ of the RRP of things like MacBooks & Surface devices.
I think I paid £100 less than the RRP on the 8GB/512GB M1 MacBook Air just before Christmas and it had only been on sale for a few weeks. I was browsing at the right place, right time I guess.
