Well, heh, until you receive the item it's not really a "sale"..
... And if you never receive the item it's just theft. Doesn't matter that they say "ALL SALES FINAL".
How did you pay? You said it wasn't paypal. If it was a credit card, dispute the charge.
PM me with the email that you're trying to get a response from -- the one you're not getting a response from. I'd be curious to see if they responded o me as a "prospective" customer...
