Be warned guys, just got this today:
Greetings from Amazon Payments.
We are writing because it has come to our attention that you have opened multiple accounts.
Amazon WebPay has a combined sending and receiving limit of $1000 per month per user. Multiple accounts opened to potentially enhance this limit will be closed.
All pending transactions have been canceled and your Amazon Payments accounts closed.
We appreciate your compliance with this matter and thank you for your interest in Amazon Payments.
Sincerely,
I didn't do anything new. Been doing the same transactions for over a year now and its been a week since I used this account, so it doesn't seem like anything in particular triggered this action.
