Andrea, if it's any consolation, I've heard from many people that internet sales for almost anything are slow during the summer. I know that last year my Google Adsense earnings decreased during the summer. My June was okay, but fully expect July and August to decline. I'm not going to let it bother me. I hope.
If I weren't expecting a baby in 3 months, I wouldn't be worried. It's just that I'd hoped this would provide some recurring revenue. However, I'm not going to get too worked up over one month. I'll have to see how the summer goes. I'd just prefer not to have to wind my earnings down to peanuts, like I had to with my first child. I know I can build things up again, but it would be nice if the cash register kept ringing...even slowly!
