Did you purchase it directly from NP Bank or from another user. I am not sure about from the NP Bank, maybe immediately would be my guess. But from another user can take some time. Some you may need to remind to send the np's on over to you via a pm. IF not than take the info you have to a mod or RJ and let them know what tanspired and what you did to resolve it with the NP seller of NP$.
The NP$ bank transactions are done manually. I handle them myself and usually pretty quickly. My office computer and my iPhone will both notify me when an order is received.
