Hi,
In some countries, paypal won't do a bank transfer, only a credit card payment. Maybe you are in one of those countries. If you are in U.S., you are just missing the "choose payment option" part of the paypal page.

If you want to pay directly via paypal, please send $30 for six months to my email address. Please don't send $5 for one month, it takes too long to track payments for that to be an econonmical way to do business.
