Payment of a fixed amount.
The Merchant offers to the buyer an option to pay for a fixed price product in any currency acceptable by ROBOKASSA.
If payment is made in any other currency, the Merchant will receive an equal amount in the currency it had previously chosen.
The ROBOKASSA Payment Button is placed at the payment page of the Merchant's website.
After clicking this button, the buyer will be redirected to ROBOKASSA website, where he can choose the method of payment.
