Payment Info
I almost always take PayPal for payment but I can take other forms of payment on request, including money orders and Google Wallet. Of course, I'm always open to trades so if you've got something I want and you want a mod performed, let's work something out!

If you desire USPS Priority Mail, UPS or FedEx, let me know and I will calculate shipping for you based on your ZIP code (or country) and weight.
