Brian, first of all welcome to RG.
If you have used paypal you'll need to wait 10 days until you're able to open a dispute on your payment and paypal will only refund if the item is not delivered. If the quality is not what you paid for they will not care, it will be a problem between you and the seller.

If you used Western Union or other payment method I'd advise you to contact your credit card company and see what the best option is for you to cancel that transaction before it goes through or if it has gone through already to do a chargeback on the transaction.

I can clearly tell you that even if you receive a replica you're paying wayyyyyy too much. The best ceramics Subs go for around $400 or less. Check BK's section on the collectors forum for the best ceramic subs.
