Mystery solved...

Remember I said a while ago in this spot that I had recieved two free WARHAMMER 40K books, and I couldn't for the life of me work out why, or even how?

I just got an e-mail from SFX saying that they're printing my letter, and could I send them my postal address because the Black Library gives two free books to everyone in the letter column. I had a letter printed earlier this year, but I forgot about it.
