Like Scott said, if you used a credit card, do a charge back. Usually you only have 60 days to do this, unless its outright fraud.

If you no longer have the product in your hand, you could try to argue fraud and that they stole your money. Probably won't fly, but its worth a try.

Beyond that, maybe try to sue them in small claims court. Hard to say if you can file in your region or not. You'd have to argue even though it was shipped to you, it was sold in your state. Heck, if you had to pay sales taxes on it, I'd argue you bought it in your state. It would be much better if they happen to have a distributor or some form of business in your state.

If you won a small claims, you could probably get the money back pretty easily after that. Just hire a collector and they'll go sieze something from them. <img src="/forums/images/graemlins/smile.gif" alt="" />
