How to Disagree Like Civilized Gentlemen

A WINNER HAS BEEN SELECTED!! Alright, it's time for the third and final chance to win a signed copy of my book “Curse of the Masking-Tape Mummy.”  

Again, to enter all you have to do is leave a comment on this comic (How to Disagree Like Civilized Gentlemen). The winner will be selected at random on Thursday morning (Feb 23rd).  Again, I will ask a question that you can, but are not obligated to, answer.

Today's question: How much would you pay for a digital, DRM-free version of one of my books?

Just curious.
