Hey, saw on Rock, Paper, Shotgun that Amazon.co.uk is now selling digital download PC titles. This is good news as the UK price is often cheaper than the US price. Hopefully they offer good sales down the track like Amazon.com. Here's a few prices, may be launch specials not sure (Blood Dragon is at least). £9.99 equates to roughly $17AU. I haven't actually bought anything but hopefully you just need to use the right billing address as per Amazon.com.
Far Cry 3 £9.99
Far Cry 3 Blood Dragon £6.99
Anno 2070 £9.99
I just hope this doesn't mean they start cracking down on purchasing from other countries.
