Thanks for the link!!
I didn´t noticed that this was a link to a german shop at first.
There the normal orders were possible (the postman collects the money from you and then gives it to the shop, or "automatic debit transfer system" ("Bankeinzug" in german) don´t know if this vocab is right.
I think these methods are more safe than giving your credit card number in the internet, so I don´t have a credit card yet.
Think I´ll get W8 round about end of november
