Best Buy is giving away $500 gift cards to the first 500 callers. They email you your gift card and it does work. I tried mine this morning and got a TV. Call 631-403-2022 and give them your email address and name.
It is not a scam, and no one got taken. It is a poor excuse for a joke that, IMO ought to get the OP banned.
It is a "how to keep an idiot entertained" message.
