I'm not sure exactly when, but at some time tomorrow, March 24, the first 200,000 people to signup will get a coupon for a free Suave Product via their Facebook page. You can follow them now if you want, but I'll also update HIF's Facebook page as soon as it goes live.
Of course, with almost half a million freebies available, you won't need to be too fast. These should last for around 24 hours, so don't fret about the giveaway being announced while you're in a meeting or class. Although I imagine constantly refreshing HIF while your boss is giving a powerpoint presentation would be the perfect way to a promotion. It shows multitasking skills, right?
