Scam Month?

Weird.  3 different scam e-mails have turned up in my e-mail spam folder since yesterday.  Is February International Scam Month?  At least there is some variety.  One claims to be from the UN, one claims to be from a US Army Sergeant in Afghanistan, and one from a DHL courier.  The DHL courier wants to give me a 5.4 million dollar "ATM VISA CARD."  Too bad, I don't have $245 handy at the moment to send them for the airport fee.
