"Giving Away 1 Prize A Day, 365 Days A Year!"
I've won three times (Fandango Bucks, Chevron GC, Amazon GC) and although there was a shipping error on the second one, it was resolved amazingly fast via email. Their customer support is out of this world (in a good way - not literally!). I don't know how they can give away so much free money, but I love it!
"Free Licensed Software Daily!"
They make deals with software companies to give everyone free copies of programs you'd normally have to pay for! Everything from screensavers to file converters to image editors to CD/DVD burning progs to random stuff like police sketch software or biometrics analyzers. They also have a "Game Giveaway of the Day!"
