I don't think there has been a further discount in line with the US.
The price cuts were on the larger SSD options, and I'm pretty sure they've been passed on.
Bear in mind that the exchange rate is currently £1 = $1.25 (read it and weep)
but the UK prices include VAT at 20%. You don't need a calculator to see that by the time you've divided by 1.25 and then multiplied by 1.20 you're only a couple of dongles away from $1 = £1... then
someone has to pay for EU/UK product certification, stricter statutory warranties and painting a £ sign on the keyboard...
For the iMac 5k, 3.6GHz 8-core, 64GB, 2GB SSD, Vega I'm getting:
UK: £4,544 vs US: $4,849
So if you work it out:
$4849 / 1.25 = £ 3879, but then x 1.2 for the VAT = £4655
...so the UK is actually getting it for slightly
under the odds. Don't complain, lest Tim Cook checks today's Sterling rate...
I remember the good old days last century when when the £ was higher, VAT was lower, and UK computer prices were quoted
excluding VAT anyway - and they were
still the US price with the $ changed to £, and grabbing a cheap flight to New York to grab a PowerBook was a viable proposition... Tell that to kids today and they don't believe you...
