Guess you are right, I know that for the zync it certainly had the waiting period, but yet for the Costo which is a charge card let me do two within one month. I also know that you are allowed payments every 48 hours? So far that has been my experience.

I like PenFed and BOA for this type of issue. PenFed and BOA allows one to make payments before a balance is posted. I don't like AMEX for the reason that you decribed. I've always had to pay through my bank to force a payment to AMEX. But I prefer paying directly to the bank who I owe. [/quote]
This only applies to the FIRST month after activation. After the first statement is cut, you can make a payment once per day if you want.
