The Iyanden supplement digital copy is more than the Eldar Codex digital copy itself, but only if the Eldar Codex is bought through an e-reader or android market that doesn't also sell the Iyanden supplement? It's a little confusing and I think needs some polishing but cheaper versions of digital copies is pretty cool, although it takes more sales away from the stores trying to sell this already crazy over priced GW stuff.
