I'm just off the 'phone to an amazon.co.uk service representative.
Because amazon.co.uk fulfilled the orders for £199.99 for the Premium edition, I was a bit pissed off having payed £299 at the same time (13th of September).
As recompense I got a £5 gift voucher.
Get on the 'phone!
Ask for more than £5 - I plucked that number out my head. Wished I'd asked for a tenner... also it will be judged on a case-by-case basis.
Cheers!
Can I just chat them?
