The idea of buying $1000 money orders to get 501 MR for $1.95 fee is mind boggling to me. The time spent and velocity needed to be achieved to get significant points doesn't seem worth it. And we're dealing with AMEX...I'm going to guess if you make $30k of money order purchases in a month you're getting shut down. And that assumes that Post Offices or Money Centers will even run an AMEX debit card as a debit card.
