Can't use PayPal? There is only one other option:

Skrill (aka Moneybookers)

If you wish to buy using Skrill, go to our store, add your items and sign up. Then send the correct amount of money as shown in your cart to via one of the above services. Then email a list of the items you have purchased so they can be added for you.

Sorry for the manual process. Your items will be added as soon as I see the request email. It may take a few hours if you send in the late hours of GMT.
