10. Can I pay via PayPal?

Yes, certainly!

Here is what you have to do:

During the Payment Step No. 3, select the PayPal option:

However, this option will not appear for all currencies (it works only for major currencies like USD or Euro). So make sure that you go to the right sidebar, to the Change Currency tab, and select USD – U.S. dollar (or Euro, or another currency supported by PayPal):

This will work no matter what currency you have on your card (the conversion will happen automatically, according to the exchange rates of the day!)
