Fourteen years ago, I began a webcomic called Shortpacked!  It was about people who worked in a toy store and told jokes about Batman.  Anyway, to celebrate, I put up a coupon code on Twitter yesterday for $5 off any order of books from my online store.  (Surprise, the code is SHORTPACKED.)  Any books!  Not just Shortpacked!, but Dumbing of Age, It’s Walky!, or Roomies!.  Today, the code still works!  So use that knowledge how you wish.
