Based on this then, you are looking at around €1.50 per CD - also, the calculation is based on lower UK CD retail prices and on the author's admittedly "lowish" rate of 14%.
That considered, total to artist, in practice, could quite easily be €2.00 per unit.
Not a huge amount, but a good deal better than "less than €1"
(Would also agree with Elefantfresh's approach BTW)
Radiohead also offered a special discbox version of the album - you pay £40stg and you get to download the album now, and then some time between now and December, you get the album on CD and on vinyl plus a bunch of artwork and lyrics and stuff and an enhanced CD including extra tracks and pictures. All in a special book.
So even though we could have got it for free, I know several people who are perfectly happy to shell out for the limited edition stuff. Radiohead fans are obsessive collectors!!
Wikipedia quotes a Gigwise article article saying that 1.2 million copies were sold with an average price of £4 each. If that's true, not bad going at all.
