Well, I thank you all. I waited for Paypal to open and got what I suspected. It is a scam. So, just in case you are unsure about Paypal transactions, here is what they just sent me: Good luck and good selling.
You’ll know that an email is not from PayPal when:
The email uses a generic greeting like "Dear user" or "Hello, PayPal member." We always address you by your first name and last name or the business name on your PayPal account.
The email requests financial and other personal information. For example, an email from PayPal never asks for the numbers of your bank account, debit or credit card, or driver’s license. We also don’t request your email addresses, your full name, your account password, or the answers to your PayPal security questions.
The email includes an attachment or a software update to install on your computer.
We will never ask you for money in an email, and we will never ask you to send money through Western Union, MoneyGram or any other third party money transfer service.
