I also want to stress that I do not want to say that anyone using Affiliate Codes was "hiding" anything from me. I assumed everyone knew about codes; clearly I was mistaken. I posted a link myself, when "Lies My Teacher Told Me" went on sale. I hope no one felt I was hiding anything from them. I just like the book, wanted to share, and didn't see why NOT to post an aff-link.
I do apologize dearly to anyone who clicked my link not knowing they were giving me 4% of the sale.
