My Amazon account says amount due 0, due date 10/19. And it shows a purchase along with the new balance. Can I make a payment or do you have to wait for a statement? 

 When asking for a cli is it best to have 4  monthly payments reporting before asking  or ask after account has been open 4 months? If I can't make a payment now it will set me back a month because this payment is due 10/19 and the next one will be due 11/19.
