Staples is running a promotion called Gift It for Free that is a sweepstakes that will have 10,000 winners who can fill up a shopping cart and get all the items for free. The promotion is running until Christmas Eve so visit the site and enter to win.
The promotion came to my attention because a rep from one of their agencies emailed me about it and about their social media efforts for the promotion, including a Facebook fan page, a Twitter profile, and several YouTube videos. They've created a character called Coach Tom who believes there should only be one winner in anything (a play on the 10,000 winners) and they have fun with that theme with the videos. I've pasted one below and if you click through to YouTube you'll see that there's several videos and they're pretty good.
