Old Navy is jumping on the celebrate-a-Facebook-milestone-in-an-over-the-top-way craze with a 30% off coupon feting its 5 millionth Facebook fan.
The coupon is a bit unusual, though. As the video above details, it's actually a photo of dozens of people holding up placards. The coupon, which you can see below, can be redeemed by either printing the image out or showing it on your smartphone.
The ad agency behind the effort, Crispin Porter + Bogusky, is a big believer in thanking fans in memorable ways. The agency worked with Kraft Macaroni & Cheese in April on a /nearly 7-minute song thanking all 4,800 fans who "Liked" a recent post. Meanwhile, AT&T, not a Crispin partner, also created 500 custom YouTube videos to thank fans when that brand hit 2 million Facebook fans.
