I'm glad to let everybody know that Y! stats are back. They worked on my account all day yesterday and it was probably just a glitch. They didn't contact me yet. The drop in sales was probably just because of Mother's day weekend, but I can't really say, because I don't have too many sales anyway, since I just started 10 months ago. I'll start promoting more and don't rely only on search engines anymore. Thanks for your support, everybody!
