The prices you have quoted in Norway for books are truly frightening. We in the UK complain about high prices compared to the USA - it just about works out £ for $, meaning if something costs £10 in the UK, it probably costs about $10 in the USA, and the exchange rate is currently approx $1.47 to £1. But there are vast differences too. I also read today people were complaining in West Virginia the price for unleaded petrol has hit $3 a gallon. In the UK today it's over $8 a gallon. That may be something to do with the amount of tax on petrol here, but still, sometimes you feel you're just being exploited, because the prices they set are what the market will stand. The beauty of ebooks is you can buy them anywhere, from the comfort of your chair. You've got the whole world to shop in!
