If you live in Europe you can deposit directly into our bank account there, in a pinch you can do the same in Australia. If not then it's PayPal. You can draw money from your credit card or bank account (limited to a few countries). What country are you in?
I'd suggest sending a mail to Veynom (email@example.com) asking for the account details then (I think the european account is located in Belgium). Otherwise, if you're using Paypal, click on your CP amount, then on "Support the Combine" and from there on the paypal button to donate. Don't forget to include your handle :)
