I pay for crysta with my credit card. Don't use click and buy nor Paypal.
And it is no longer a set amount. Can type in exactly how much you want.
Every payment you make goes through some kind of processor before it reaches its destination. Even with a "direct" payment, your card carrier e.g. Visa or Mastercard handles your transaction. By the way, PlaySpan (the provider of creidt/paypal/game card dransactions) is owned by Visa and should be considered as safe to use as "directly" paying SE. Since you can now pay the amount of crysta you need and not 1 crysta more, there is NO reason to be complaining about this. The only way the "direct" payment can make things better is if it can be made automatically recurring.
