Price difference in Creative Cloud?

Can someone explain to me why it costs so much more to purchase Creative Cloud if I live in the United Kingdom compared to somwhere else. There should be no difference, it's a digital download! (no shipping)

If I bought the complete package it costs £46.88 per month in the UK.

If I bought the complete package in the US it costs $49.99 bearing in mind that the current exchange rate is $1.5 to the £1 and therefore if exchange rates were used it should cost £33.20 in UK sterling, that's a price hike of approximately 30%

If i bought the complete package in Australia it costs $49.99 bearing in mind the exchange rate is $1.5 to the AUS$1.56 and therefore if exchange rates were used it should cost £31.99 in UK sterling, that's a price hike of 32%

it's simlilar if you bought it in Japan and many other countries.

So please Adobe can you explain to me why this is so, I'm a bit puzzled.

Also if I paid in US dollars would I recieve the product for the US Dollar price?
