May be. But in month to date royalty report shows 10 net sales. Further customers can return till seven days. If I sold 2 books (for example) in last seven days and two refunds, how come it shows negative royalty. It must show zero!
You posted this on Sep 6, so there were less than seven days in the month! (If you're not using the month-to-date report, you should be.) Anyhow, I'm skeptical that one can't return a book on the eighth day. What if one didn't OPEN it until the second week, and found it was blank or rubbish? Amazon is on the side of the customer.
I've always figured 2 percent returns. But oddly, in July, August, and so far in September, I've had none.
