I publish my app in android market on 1st May. In first and second month earned above $500 and got my payment in July and August respectively. In both months admob mailed me for that on 2nd day of the month. But for this month my revenue is under $400 and I do not get any mail till now. However my account balance is not deducted. I've read on admob help that lowest limit is $100. So why my payment is not processed. Is it normal?
