No Tax ID is required or even asked for during the registration process. All they ask for is basic info like name, business name, address, email, and phone number. I don't know about the sales tax - I live in Montana and we never have to pay sales tax. It looks like this offer is only good for people who received the email. I figured more peeps from here might have received it - i almost deleted it.
Here's the whole email:
