Nikon D3 and 24-70 kit
The price isn't what makes it a scam. It's an auction so you'd expect the final selling price to be higher.
However, I'd always be concerned with the payment method: "BANK DEPOSIT OR BANK TRANSFER ONLY."
Unless I could pick up the item in person or pay via a secure & trusted method I would not pay - simple as that. And a bank deposit or transfer is not trusted - trust me on that.
