Pirates!
Spammers must expect you to really believe in things like the tooth fairy. Here's an example of a deal for outrageous savings sent in one spam message. You'll note that the prices are below what the original vendor charges its wholesellers. Conclusion? This stuff is bootleg pirated software. Example of probable pirated software:
Windows XP PR0 2002 - retail: 270.99 ; our priice: 50.00
Ms 0ffice 2OO3 PR0 - retail: 499.00 ; our priice: 110.00
Ms 0ffice XP PR0 2OO2 - retail: 579.99 ; our priice: 100.00
Ms Windows 2OOO PRO - retail: 266.99 ; our priice: 50.00
Norton Anti virus Corporate 2OO3 - retail: 69.99 ; our priice: 15.00
Norton System Works 2OO3 Deluxe - retail: 96.99 ; our priice: 40.00
What do you get in reality? They tell you that you only get the CD and no documentation. But it may also be a CD with a key that doesn't work or that alerts the vendor to pirated software. You may also get legal process from the vendor directing you to remove the software or worse you might be charged with a crime. That's if you get anything at all. When you deal with unreputable sources, you can also expect to send money and not get anything at all.
Deals like this aren't deals at all. The only one that benefits is the spammer, which in this case is a person in a foreign country who will probably have a new e-mail address and identity in a couple of days.
If the deal sounds too good to be true, it isn't true. Don't be a sucker and fall for a con. Don't be a spam enabler - never buy anything offered in a spam e-mail.
