I was wondering if anyone knew how long you have to pay once your order goes through, when I googled it, it said usually 4-8 weeks, but it must have been mistaken, i ordered it two days ago and I just got an email from the saying my order has been processed and a payment link will be sent in a separate email, its for a receiver barrel combo for the m1 garand, I did not expect this so I dont have the cash for it today, does anyone know when payment is required? Thanks for the help
