If that is the case, then it may be the cheapest deal yet? Use virtual credit card number, and sign up several times. For example, sign up 10 times, will cost about $79.99 and you get 25,000 AA miles

Any holes in the approach above? Problems, Issues that will come up if attempting to do multiple registration with virtual credit card numbers?
