I wish more people knew how to read email headers and look up an IP address, but I suppose that's like saying "I wish more people knew how to change their oil and do their own tire rotation." These gift card scams are picking up in popularity with Christmas approaching, there's no such thing as a free lunch.

Generally if something looks too good to be true, it isn't true. And if you're being offered something for nothing, then you're being scammed or you are the product.
