Hmmm - strange conversion rate:
US - $29.99
Canada - $39.99 (English and French price - not clear if this is US$ or CAD) = $42 US (if in CAD)
UK - £79.99 = $132.31 US
Australia - $119 (not clear if US$ or AUS$) If AUS$ then equivalent to $128US
France - 35 Euro = $51.32 US
So which country is the rip off version? You guessed it!
What is particularly gauling (no pun intended, honest) is that the EU is supposed to be a single market so why is the UK version $80 more expensive than the French?
More interesting is the discount price for Microsoft Office 2010 Pro for Students - UK under £50 ($80 for US students) which is a pretty good deal if you need the works.
