Most shameless spam mail I've seen so far. They pretend to be Apple selling Adobe and M$ software at huge discounts. It looks quite real and I almost fell for it. All the links point to shady randomized URLs, of course.
But, to be fair, I really don't mind if Adobe and Microsoft get ripped off big time. They rip off their customers too, so fair's fair.
