So based on the previous posts, and new T&C that you can't "Provide yourself or Authorized Users a cash advance from your credit card", the practice of $100+$100+$50 cc funding and then withdrawl to bank will get you closed down, how about instead of bank withdrawl an ATM withdrawl? I avoid this because of the $2 ATM fee, but I am just curious.
Anyways, serve's $250 monthly maximum plus limited daily transactions is a lot of work for a little reward.
