h) I entered my credit card details and submitted, but couldn't proceed because zip code and state are mandatory. I do not stay in the US, so those fields don't make sense to me. You are alienating non US citizens.
Try this link [1]. It appears to be slightly different from the one in the original submission.
This link allows donations in various currencies, although some are only available via credit card, while others require the use of PayPal.
The credit card details form that displays after clicking "Donate by Credit Card" offers "Outside the U.S." as an option for the "State". Also, there is a "Postal code" field, which is hopefully more friendly for those without a Zip Code. Finally, there is a drop-down list for selecting "Country/Region".
There are also alternative donation methods, described here [2].
