So I just got off the phone with my GW rep...
If you would like Codex: Iyanden PLEASE, PLEASE, PLEASE let me know by this Friday.
This book is going to be handled just like that "Death from the Skies" supplement at first, meaning that there's only a limited number of them and they are likely to sell out. Because GW hates me, they go on sale through the GW website starting THIS FRIDAY. This means that I will not be able to call and order them for people until the following Monday, at which time the first wave will likely be gone.
What I can do is order them for the store from my personal account and then have GW credit BG for the difference at a later date. Because this is the only way to make sure the store can get them for you guys, please let me know if you're interested in it.
Codex: Iyanden does require Codex: Eldar to function. It is NOT stand alone.
Thanks, dudes.
