Patreon has an inability in not adding one time payment option on the backend, however it is easy to make it a one time payment anyway as it is supposed to be. After placing your order and the payment processes, go to https://www.patreon.com/pledges and click the delete button next to the ScentedPotterGTA pledge. This makes it a simple one time payment as it is supposed to be, we do not do nor want monthly subscription payments for anything. Delete the Patreon Pledge after you have finished paying for your order.
