I know a lot of people are throwing their hands up and just admitting defeat saying the money is gone. But you should at the very least contact your credit card company (if you paid that way through paypal - and you should have).
For anyone thinking of doing a chargeback the rules are generally listed as six months, however there are exceptions and extensions that can be tacked on. One extension being for pre-order products that are being hand assembled. And this most certainly falls into that category. For guys that have the money to blow, great, wait it out and see if you get that last minute hail mary. But for others who are on a tighter budget, do not wait any longer, at least make that call and see what recourse you have.
Paypal is a dead end as they will do absolutely nothing after 180 days unless they hear from your credit card company.
