For me, the best way would to pay with Crysta with my credit card (which does not have 3-D Secure). As I mentioned in
another post, the only way to do this would be to buy the UlimatePay gamer cards at retail stores.
ClickandBuy requires a 3-D Secure credit card in order to even open a new account.
Paying via PlaySpan with a Paypal account forces you to pay with the bank account linked to your Paypal account.
I paid via Paypal for the next pay cycle. I might choose to buy a gamer card from retail stores in future cycles because when I pay by Paypal, I want to use my credit card, not my bank account. -_-
