Yes I know I messed up :/ I found out my mistake after I bought the two books myself. It looks like Lulu won't let me change it without making me buy another proof copy. It's only on the Lulu page the title is wrong though. I think it's unlikely Lulu will mess up a order since they only print a book if someone orders it.
How many of these have you bought? You probably have a bigger library of my books than me soon :p
