Have to say, I did check the prices at Apple earlier out of interest and they don't seem to be as deeply cut as in the US.
That's because in US$ terms we've already had massive discounts as the Pound has fallen in value against other currencies.
For example, with today's discounts a 2.4 MB costs £1,088.00. Subtracting the VAT makes that £925.95. That's roughly US$1424.35 at today's exchange rate.
The US store has that model on sale for $1,498.00 at their special Black Friday price, giving us in the UK a Black Friday saving of $73.65 over the discounted US price, roughly £47.87 cheaper.
I suspect January is going to see some pretty hefty price rises on Apple kit to UK customers.
MatLane, you'd be better off getting that MBP as soon as possible. I don't think we'll see the prices cut on Monday either, as Apple are going to absorb the VAT cut to cover their currency losses.
