If the subject is Amazon.com, that doesn't mean they sent it. Never click on those. Write an e-mail to them yourself and tell them what you got. Lots of people try to send very "official" looking e-mails from different companies. I have been getting e-mails from my dead niece for two years, starting the day after we buried her. Someone stole her e-mail address book. Such a shame how nasty some people can be.
