For today only, become a fan of Babies-R-Us on Facebook and get a free $5 e-Giftcard. The card can be used in-store or online and it expires on 2/20. The one downside is that this place only sells stuff for babies. It's been a while since I've played with a pink rattle, but whatever, it's free.
Coincidentally enough, there's a Facebook page for Hey, It's Free! where new fans get 40,000 Awesome Points. Possible rewards from your points include high-fives from me or even letting me crash on your couch as I pass through town!
