Shipping is included in today's deal, making your Groupon a $9.94 total value.

Numerous scientific studies have cited the dangers of driving while chatting on a cell phone. A 2005 report from the British Medical Journal states that those who do engage in the hazardous habit are four times more likely to get into a car accident than those who keep all their senses trained on the road. Despite many states outlawing the practice, countless drivers have failed to heed the moral of the story: driving while talking or texting can be and often is fatal. With this in mind, April 30 has been designated National "No Phone Zone" Day. The Get Off the Phone business is offering this Groupon-exclusive deal to further achieve their mission of spreading the no-phone message to communities across the United States.

Many drivers who talk or text while driving don't do so out of malice, but out of carelessness. A bold, text-based reminder from neighboring cars works as a little slap in the face that says, "Hey there, haberdasher. You're being stupid." The sign is affixed to your car window via suction cups, a la the "Baby on Board" signs of yesteryear and arachnid-powered superheroes. In reality land, it's hard to be a superhero, but it's easy to participate in group action that sends a clear message: get off the phone!
