Walgreens, COSTC0 and Amazons

Free points, vouchers are waiting for you emails...what happens if I click the links!?
COSTC0, the last O is a zero (0).

BTW, where does these scammers get your email addresses!?

If you click the link, you'll either be taken to a phishing page where they'll try and get your details or to a page that tries to download malware.

And they could get your email from anywhere - a form you filled in for a competition, a website that you were registered on that was hacked or from a friend's contact list if their email was compromised.
