how does Amex Serve transfer works? do i need to open Serve account?
You would need to buy a amex serve prepaid card and register it online. Once you've done that you can send / receive funds and withdraw at ATM.
This offer is only good for the rest of the weekend. Will probably just withdraw cash myself on Monday and buy what I need.
Still have $460 in serve funds available. Bitstamp +3%
