Good day,
I have been told by Sir. @CozPatch that instead of Paypal, members can pay with a bank account or credit card (it is still processed by Paypal, but doesn't require an account with Paypal).
For alternative methods of payment, members need to contact @Sbenny directly.
Greetings Angmund,
As far as I know, the services offered by PayPal in Azerbaijan are limited only to sending payments via your account.
If this does not work for you, you may pay directly from your bank account/credit card.
To do this, in Account Upgrades, you simply click on the "Access to NSFW section" Purchase button and you'll be redirected to PayPal. Instead of logging into PayPal(log out if already logged in), choose the "Pay with a Bank Account or Credit Card" option.
You will then be redirected to the checkout page where you fill in you banking/card details.
If this still does not work for you, then the only other option as Mark A stated, is to contact Sbenny via PM and arrange an alternative method of payment.
I am closing this question and moving it to Answered Questions as this question has been resolved. If you have any other questions please post them in our Questions Area.
