Well, you may have 2 accounts because even though I don't the T&C of Amazon Payments, Amazon itself, allows you to have more than 1 account.

Now if the SSN and everything else is the same for ACCOUNT A and B and you do A-->B and then B-->A, there's a 99.9999% chance that you'll be caught.

You can do A-->C, B-->C, and keep the payments $600 or below...I'm sure there are people that have transferred $1000 with no problems, but the best way to keep under the radar is to transfer small amounts over a 30 day period.
