I often poke into Amazon to see how my Cookbook is doing, and the sales ratings are usually all over the place. But today, for the first time that I've noticed, it hit #1 in one of its categories (CAD). Not too bad in the other categories either!
The ratings change by the minute, so I took a screen cap for posterity. (Though I'll check tomorrow and the numbers will probably be well into double digits ;-)
