As an Aussie I learned early on not to even bother legitimately trying to purchase from US sites such as Fictionwise or Diesel, since the GR bit me every time. I've been happily getting epubs from the book depository in the UK until a couple of days ago, when a download failed due to GR (kraken by china mieville). Not a happy camper
I've spent hundreds of $ on ebooks but GR is doing its best to stop me.
And don't get me started on americanisation of english, or kids walking on my lawn...
