Payment is due within seven days of auction close. If you wish to bid and buy for an extended period of time, I don't mind as long as you finish within 2 weeks. Please let me know when you are ready for a combined invoice and I will send you one, otherwise Ebay will send you a generated one without the discount. Paypal, checks and money orders are accepted. If you are sending a payment through the mail, Please remember to include your Ebay ID or item number with your payment.
