I've been getting those for quite a while now but the latest scam is an email from a friend telling me that a particular link is really good and I should check it out.
It appeared to be completely genuine until I realised that my friend's use of English was better than that so I called her - she was nowhere near her computer and this email had gone to all her friends and family.
Needless to say, if you get something even from a friend with a suspicious link - delete!
Cheers
