And this is the big news: to celebrate the launch of All About Homophones, your readers can get $10 off any order at www.all-about-homophones.com! To receive the discount, visitors to the site need to enter "FUN" in the customer code box during checkout. The coupon code is good for one week, through February 2, 2009.
With that discount, the ebook version will only set you back $17 and some change. If you've been curious about the book, now's definitely the time.
ETA: My full review of All About Homophones is now up and available here.
