The only correct way would have been for the buyer to suggest using escrow to the seller. Since it was a scam, the seller would have backed out quickly. For $1500, it's going to be via escrow.com with a credit card. It's the only sane way, even if it is completely legit. Protects the seller, too (because such scams can happen in the other direction as well).
