Why did this come in the mail?

This is pretty neat, its some type of sports-device, branded with the Grand Theft Auto Logo. However, I have no idea how it got here. Actually, that's not completely true. The postman got it for me, but who gave it to him? And why? Can anyone shed some light on this? All I could find was that some places got this as a promotional item along with a press release. There is no reason they would send me that. So what gives?
