pending means that the payment hasn't gone through on the buyer's side. whether their credit card didn't clear or whichever else reason. could also mean that they are doing a soft review of your account, but its more than likely the first reason
Ax, it's not that king of 'pending' b/c I have not gotten the 'do not ship' email. this is something different and I think it's b/c of the current AM glitch.
One thing I've noticed is is if you have over 10 pending orders from hours ago and theres no technical issues on amazon. Then your most likely getting banned soon.
