The base M2 macbook air is $1499 in the US. Whereas it is £1549 in the UK. Previousely Apple just replaces the currency but uses the same figure. Now Apple has increased the uk price. Thank you Apple.
One difference is taxes, the UK price includes VAT whereas the USA price adds tax at checkout so they aren't really comparable numbers. Further, the pound has fallen so you'd expect they have to increase the GBP price to maintain margin.
Dollar has been appreciating rather fast the last few months compared to the pound and euro.
