What she said. I zoomed up to 2,000 or something the first day of my preorders because it changes from day to day. If you sell one copy in a day, it will immediately shoot you up to 100,000. You could go crazy watching them. Plus . . . my editor says such a small percentage of YA/ MG sales are from Amazon that I don't have to give it a second thought!

(but it's fun anyway!)
