Currently our methods of purchasing the theme are PayPal or credit card via PayPal. As a last resort option we could possibly process a manual transaction through Google Checkout, however I imagine you'll still need a credit card to complete this as well.
Sorry we do not have other methods outside of this.
You may just ask a friend or relatives with credit cards to help you with the purchase.
Please help our moderating team work more efficiently by not sending us support questions via PM. You can read more about how AppThemes support works here. However, you can send a PM to follow up and remind me if I missed your support request/thread.
