Seconding this.
Payment via credit card is pretty uncommon in Germany, so most people here simply don't have one.
Sorry D3m0, that's not all in true.
In most cases you need a credit card, if you want to buy something outside of germany.
So I think the contrary of your statement is true, too.
But I think also the PayPal option is a good thing, for those who haven't a credit card.
